When: April 14th, 2022 – 3:00 pm

Where: in-person seminar, Sala Seminari, VIMM. Recording available on Mediaspace

Abstract: The clinical assessment of brain pathologies has been increasingly dependent on advanced magnetic resonance imaging (MRI) techniques in order to infer lesion pathophysiological characteristics, such as hemodynamics, metabolism, and microstructure. Advanced techniques in computed tomography, MRI and positron-emission tomography have further improved the visualisation and localisation of brain pathologies especially in neuro-oncology, providing target definition for various therapeutic modalities. Additional refinements of newer imaging methods, such as MR Spectroscopy, functional MRI, diffusion MRI and diffusion tensor imaging, have allowed a more detailed and accurate definition of tumour features and the relation with eloquent brain tissue. Nonetheless, these imaging methods have acquired a pivotal role in presurgical planning for brain surgery.

Settimana Mondiale del Cervello

When: Apr 7th, 2022 – starting at 10:00 am

Where: Sala dei Giganti, Palazzo Liviano, Padova

Abstract: “Le stagioni del cervello” è il tema dell’edizione 2022 della Settimana mondiale del cervello: conoscere come funzione il cervello nelle varie fasi della vita, come proteggerlo fin dalla giovane età e come mantenerlo attivo nell’invecchiamento è una priorità di benessere e salute pubblica.

A Padova il 7 aprile presso la Sala dei Giganti si tiene una giornata dedicata a questi obiettivi: in mattinata viene dedicata attenzione alle fasi evolutive del cervello con interventi educativi sui tics e il loro stigma, sull’impatto della musica nell’allenamento del cervello; a seguire, un momento musicale con studenti, studentesse e docenti. Il pomeriggio è dedicato agli stimoli per mantenere il cervello attivo e sano il più a lungo possibile. Si tratta il tema dell’esercizio fisico, del benessere psicologico e dell’attivazione cognitiva con stimoli e proposte pratiche.

Coordinata dalla European Dana Alliance for the Brain in Europa e dalla Dana Alliance for Brain Initiatives negli Stati Uniti, la Settimana del Cervello è il frutto di un enorme coordinamento internazionale cui partecipano le società neuroscientifiche di tutto il mondo e a cui la Società Italiana di Neurologia e la Clinica Neurologica di Padova aderisce da anni.

L ‘evento, gratuito ed aperto a tutti, si svolge esclusivamente in presenza presso l’Aula dei Giganti, Palazzo Liviano.

Abstract: ….da dove vengono i pensieri, le emozioni, e come prendiamo le decisioni che nel piccolo e nel grande determinano la nostra vita? Che cosa sono il senso morale e l’etica? Dove finisce la biologia e dove inizia la cultura?

Per quasi venti secoli i filosofi e gli scienziati localizzarono nel cuore la sede delle attività mentali superiori, ed è solo dalla metà del 1600 che il cervello è considerato il centro delle facoltà intellettive. Grazie allo sviluppo di nuove tecnologie negli ultimi 50 anni vi è stata un esplosione di conoscenze sull’organizzazione cerebrale che da un lato ci hanno fatto comprendere come il cervello umano non sia speciale, ma che la sua complessità non è altro che il prodotto di un evoluzione di meccanismi più semplici che sono presenti in tutte le specie dal nematode all’elefante. Dall’altro stanno emergendo risultati che indicano che alcune delle funzioni cosiddette umane non sono altro che il riciclo di meccanismi neuronali per funzioni sensori-motorie più semplici. Questo permette una nuova chiave interpretativa a fenomeni sociali che sono al momento principalmente oggetto di letture sociologiche, educative, o culturali, ad esempio il razzismo o la tossicodipendenza. Anche se la traduzione dal biologico al sociale è delicata e può essere banalizzata, non vi è dubbio che quello che è fuori di noi, cioè la società e la cultura non sono altro che il prodotto dei nostri cervelli e che molte risposte a problemi della società si potrebbero trovare nell’organizzazione e nella funzione delle reti neuronali.

Understanding learning and memory at the single-synapse scale

by dr. Marco Mainardi, Istituto di Neuroscienze, Consiglio Nazionale delle Ricerche – Pisa

When: March 24th, 2022 – 3:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: Plasticity of synaptic connections adjusts the signal flow across neural circuits to
support the acquisition and storage of information. Dendritic spines host most excitatory
synapses in the brain and incessantly remodel to meet the computational demands for
acquisition or recall of new episodic memories, or goal-oriented behavioral schemes.

Despite the obvious physiological importance of synaptic plasticity and its implications in
pathological contexts, appropriate tools for the specific analysis of potentiated synapses
are scarce. To fulfill this gap, Dr Mainardi has contributed to the creation of genetically
encoded tools allowing the expression of virtually every protein of interest specifically at
potentiated dendritic spines. This system has been applied to express (i) fluorescent
reporters and obtain maps of the distribution of potentiated dendritic spines along the
dendritic tree of hippocampal neurons or (ii) a FLAG-tagged version of the PSD-95
postsynaptic hub protein and isolate its potentiation-specific interactome. These data
provide a first cartography and molecular fingerprinting of synaptic potentiation triggered
by a specific learning task, in addition to paving the way for further studies in models of
neurological diseases characterized by impaired learning and memory.

Bridging Neuroscience & Robotics: wearable robots for innovative rehabilitation and healthy ageing

by prof. Alessandra Del Felice, Dep. of Neurosciences – University of Padova and prof. Emanuele Menegatti, Dep. of Information Engineering – University of Padova

When: March 17th, 2022 – 3:00 pm

Where: Sala Seminari at VIMM, Via Orus 2b, Padova, Zoom meeting (Recording available on Mediaspace)

Abstract: Robotic devices have seen an increasing uptake in neurorehabilitation, due to the higher intensity and larger therapeutic exercise doses they can provide. More recently, robots have also entered the market as assistive wearable devices – i.e. to enhance or integrate human body performance.

However, the human and the robot are usually considered as two separate entities interacting via a fixed and immutable interface and the robot is seen as a mere actuator of pre-designed motions.

For the effective exploitation of wearable robots as assistive and rehabilitative tools, we need to overcome these limitations aiming towards a synergistic integration of humans and robots. Advanced interfaces based on neuromuscular data and sophisticated mechanical structures are yet insufficient. We need to move in the direction of a reliable and continuous interaction, based on detailed knowledge of the neuromuscular responses to robotic training and the development of approaches in which two intelligent agents (i.e. the human and the robot) cooperate to achieve a common goal. Therefore, our Neuroscience and Robotics research groups at the University of Padova are collaborating on this challenging topic. We will first focus on the concepts supporting the use of robots in neurorehabilitation and healthy ageing, moving then to present novel Artificial Intelligence techniques to develop shared-intelligence architectures for wearable robots interfaced via the electroencephalographic (EEG) and electromyographic (EMG) signals.

Effects of transcranial direct current stimulation (tDCS) in the physiological and in the ischemic motor cortex in the mouse

by prof. Marco Cambiaghi, Dep. of Neurosciences, Biomedicine and Movement Sciences – University of Verona

When: March 10th, 2022 – 3:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: Transcranial direct current stimulation (tDCS) is a widely adopted non-invasive brain stimulation technique for the modulation of brain excitability. The direct neuromodulatory effects of tDCS beneath the electrode is considered to extend to nearby as well as distant brain areas, mainly depending on the activation state of the brain before and during stimulation. This is evident in physiological circumstances (e.g. during physical activity) but it is even more marked in pathological conditions (i.e. stroke).

My recent activity focuses on the study of tDCS aftereffects on direct and indirect modulation in the primary motor cortical area in mice while performing a motor task. We observed that unilateral stimulation is able to influence neural activity and plasticity in the contralateral hemisphere if applied during a simple motor task that activates motor areas bilaterally. This results could be of great relevance for the use of such technique in the chronic phase after brain ischemia. Moreover, in the photothrombotic mouse model of ischemia, the application of cathodal tDCS few hours after the stroke onset was observed to improve functional recovery and act on non-neural cells, by modulating microglia morphology.

Approaches to brain controllability

by dr. Michele Allegra, Dept. of Physics, University of Padova

When: March 3rd, 2022 – 3:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: A major goal of applied neuroscience is to understand how to achieve controlled perturbations of brain activity through stimulation or brain-computer interfaces with the aim of investigating brain mechanisms or restoring normal activity patterns in subjects affected by neuropathologies.

In recent years, several authors have proposed to frame this problem within control theory, a well established engineering paradigm to control dynamical systems. In this framework, a model of the autonomous (uncontrolled) dynamics of the system is used to precisely devise external interventions that, in combination with the autonomous dynamics, will steer the system towards desired targets. Three main obstacles, however, hinder the applicability of control theory to the brain: (1) a limited ability to measure or reconstruct intrinsic dynamics (2) a difficulty in realizing targeted perturbations (3) the complexity (high dimensionality) of the system. In this seminar, we shall illustrate these problems, focusing on our recent theoretical investigations of brain controllability in humans, where intrinsic brain dynamics can be characterized through neuroimaging (fMRI). We shall argue that achieving precise control of whole-brain activity by a naive application of standard control theory is currently unfeasible. Finally, we shall briefly discuss possible alternatives to realize controlled manipulations of global brain activity.

Oculomotor responses in humans and animals

by prof. Aram Megighian, Dep. of Biomedical Science, Padova

When: Feb 17th, 2022 – 3:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: Gaze direction results from the orientation of eyes in the head and the orientation and position of the head in space. Consequently, gaze direction controls the retinal image.

Eye movements can be substantially subdivided in two classes. Eye movements which stabilize gaze when animals move their body and head (or only the head) with respect to the surrounding environment. The goal of this response is to stabilize the image on the retina despite the head movement (substantially they prevent retinal slip). Stabilization mechanisms have evolved to solve this problem. They maintain visual acuity during self-motion by stabilizing the retinal image of the world with rotations of the eyes that exactly compensate for head and body movements. The neural mechanisms for gaze stabilization are highly conserved across vertebrates and invertebrates, reflecting the widespread need to stabilize visual inputs despite other sensory and motor differences between species.

The second class of eye movements are eye movements which redirect gaze. The goal of this response is to allow animals to inspect the visual field with the aim to actively select objects or features of particular interest. These last processes require cognitive mechanisms based on perception and selective attention, and on motor control based on both predictive and feedback mechanisms. An interesting point in this class of eye movements is the fact that gaze redirection at least theoretically implies to focus a limited part of the visual field on a region of the retina with a higher spatial resolution. Hence it was supposed that these mechanisms were only present in animals with a fovea. Today, on the contrary, these mechanisms were also found in animals in which a truly fovea was not present, opening interesting questions about the cognitive mechanisms regulating gaze redirection as well as the presence of high spatial resolution regions in the retina of afoveate animals.

The neural architecture of early speech perception

by prof. Judit Gervain, Dept. of Developmental and Social Psychology, University of Padova

When: February 3rd, 2022 – 3:00 pm

Where: Zoom meeting

Abstract: Despite their general immaturity, human infants have sophisticated auditory and speech perception skills. This talk will present EEG and NIRS studies with newborns and older infants investigating the neural mechanisms underlying these abilities. The studies investigate how embedded neural oscillations, hypothesized to be crucial for speech processing in adults, emerge during early human development.

The talk will discuss the implications of these findings for language development.

Short bio: Judit Gervain is a Full Professor at the Department of Developmental and Social Psychology. She is trained as a theoretical linguistic, obtained a PhD in 2002 in Cognitive Neuroscience under the mentorship of Jacques Mehler from SISSA, Trieste, Italy. She then worked as a post doctoral researcher at the University of British Columbia, Vancouver, Canada. In 2009, she took up a researcher position at the CNRS, in Paris, France, from which she moved to the University of Padua in 2020.

Her research focuses early speech perception and language acquisition in typically developing monolingual, bilingual infants as well as in infants with hearing difficulties. She uses behavioral as well as brain imaging techniques to explore the perceptual, linguistic and cognitive development of these infants and their underlying neural correlates. She has done pioneering work in newborn speech perception using near-infrared spectroscopy (NIRS), revealing the impact of prenatal experience on early perceptual abilities, and has been one of the first to document the beginnings of the acquisition of grammar in newborns and preverbal infants.

Her work has been published in leading journals, such as Science Advances, Nature Communications, PNAS and Current Biology. She is an associate editor at Developmental Science and Neurophotonics, and a member of the Governing Board of the Society for Near-Infrared Spectroscopy.

Robotics in Rehabilitation

Webinar: Università di Padova, Ulster University, Harvard Medical School, University college Dublin

When: Dec 2nd, 2021 – 3:00 pm CET (9:00 am ET)

Where: Zoom Meeting (please enroll to receive the link)

Abstract: Rehabilitative and assistive robots are a rapidly emerging field. However, their efficacy is still hampered by the lack of adaptive interaction with the end user, disregarding ongoing changes in brain and muscle reactivity.

The collaborative, international research projects SOFTAct and PRO-GAIT are setting the foundation to revolutionize wearable robots: artificial intelligence techniques will provide the framework to use cerebro-muscular biosignals to control robots. This will allow wearable robots to become a natural extension of the human body in the near future.

Our Restless Brain – Exploring the Brain’s Dark Energy

by prof. Marcus E. Raichle, Washington University in St. Louis

When: June 17th, 2021 – 5:00 pm

Where: Zoom meeting

Abstract: The core idea in this talk is that brain-wide, ongoing activity is essential for brain function and behavior. This activity accounts for 20% of the energy consumption of an adult human even though the brain contributes only 2% to the weight of the body. Brain activity associated with task performance is associated with surprisingly small regional changes in brain energy consumption. These changes are so small that they have no effect on the overall brain energy consumption. The emerging challenge for neuroscience is to understand the contribution this very high-energy consumption makes to brain function. What has been revealed over the past several decades as imaging of not only humans but also other mammals as well as flies and worms is a remarkable brain-wide, functional organization within this ongoing activity.

The objective of the talk is to provide an overview of this rapidly expanding body of work emerging from laboratories worldwide.

Short bio: Marcus E. Raichle, a neurologist, is the Alan A. and Edith L. Wolff Distinguished Professor in Medicine with joint appointments in Radiology, Neurology, Neurobiology, Psychology and Biomedical Engineering at Washington University in St Louis, Missouri, USA. His research over the past 51years (first scientific paper published 1970) has focused on the relationship of brain circulation and metabolism to brain function. He was the member of the team that introduced the first tomographic images of brain blood flow and oxygen consumption with PET. Noteworthy accomplishments during this time have been the discovery of the relative independence of blood flow and oxygen consumption during spontaneous and evoked changes in brain activity which provided the physiological basis of fMRI; the discovery of a default mode of brain function (i.e., organized intrinsic activity) and its signature system, the brain’s default mode network; and that aerobic glycolysis contributes to ongoing brain function independent of oxidative phosphorylation. Current research focuses on the metabolic and neurophysiological organizing principles of the human brain’s intrinsic activity in health and disease. He is a member of the US National Academy of Sciences, US National Academy of Medicine and the American Academy of Arts and Sciences.

Brain dynamics related to short-term memory and learning

by prof. Fritjof Helmchen, Brain Research Institute of the University of Zurich, Switzerland

When: Apr 29th, 2021 – 3:00 pm

Where: Zoom meeting

Abstract: Through the combination of in vivo optical imaging and chronic expression of genetically encoded calcium indicators it is now feasible to directly ‘watch’ brain activity patterns related to specific behaviors. I will introduce wide-field calcium imaging and multi-fiber photometry as two complementary methods that enable measurements across mouse neocortex and in large sets of subcortical regions, respectively. Specific patterns of brain-wide signal flow that occur in mice performing whisker-based or auditory sensory discrimination tasks will be discussed, highlighting salient patterns related to short-term memory. In addition, taking advantage of chronic measurements over weeks, I will present salient changes in brain dynamics that relate to task learning.

Short bio: Fritjof Helmchen received his Diploma in Physics from the University of Heidelberg. He completed his PhD thesis in Neuroscience at the May-Planck-Institute for Medical Research in Heidelberg and received his doctorate from the University of Göttingen in 1996. As a postdoc, Dr. Helmchen worked at the Bell Laboratories, Lucent Technologies, NJ, where he pioneered in vivo applications of two-photon microscopy. He then returned to the Max-Planck-Institute for Medical Research, Heidelberg, heading a junior research group from 2000-2005. In 2005 Dr. Helmchen was appointed Professor of Neurophysiology and Co-Director at the Brain Research Institute of the University of Zurich, Switzerland. Dr. Helmchen’s research is centered on the further development and application of imaging techniques for the study of neural network dynamics and neural computations as the basis of animal perception and behaviour.

fMRI-based Quantitative Mapping of Human Brain Cerebrovascular and Metabolic Function

by prof. Richard Wise, Universita’ degli Studi “G.d’Annunzio” di Chieti-Pescara

When: Mar 18th, 2021 – 3:00 pm

Where: Zoom meeting

Abstract: In the last 30 years blood oxygenation level dependent (BOLD) fMRI has taught us a great detail about human brain organisation. However, it only tells us where brain activity is changing without telling us by how much or what the baseline level of activity is. We and others are working on fMRI methods to map the absolute rate of cerebral metabolic oxygen consumption as a marker of the physiological state of brain tissue in health and disease. Development of these methods has resulted in a toolkit for assessing oxygen consumption and cerebrovascular function (including vascular reactivity and arterial compliance) that is yielding interesting results in our pilot clinical studies in epilepsy and multiple sclerosis and in the study of the healthy brain. These approaches have the potential to take fMRI to a new level of quantification of brain function required for experimental medicine and future clinical application.

Short bio: Richard is a physicist who has always worked at the interface of physics and physiology. He specialised in cardiovascular magnetic resonance imaging for his PhD at Cambridge University. In 2000 he changed from imaging the heart to the brain with a move to Oxford University as a post-doctoral research fellow, (Wellcome and MRC research fellowships). From 2006 he developed his research group at Cardiff University Brain Research Imaging Centre with a focus on understanding drug effects on human brain function and looking for ways to quantify brain function using functional MRI approaches, based on sensitivity to blood oxygenation in the human brain. This has led recently to a new magnetic resonance imaging toolkit with the possibility to interrogate, in detail, the function of brain blood vessels and to measure the amount of oxygen fuel that the human brain is using in health and disease. At the end of 2019 he moved to ITAB (Institute of Advanced Biomedical Technologies) and the Department of Neuroscience, Imaging and Clinical Sciences at the University of Chieti-Pescara in Italy, as full professor of applied physics (Professore Ordinario – chiamata diretta).

Principal Directions of Mediation

by prof. Martin Lindquist, School of Public Health, Johns Hopkins University

When: Feb 18th, 2021 – 4:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: Mediation analysis is an important tool in the behavioral sciences for investigating the role of intermediate variables that lie in the path between a randomized treatment/exposure and an outcome variable. The influence of the intermediate variable on the outcome is often explored using structural equation models (SEMs), with model coefficients interpreted as possible effects. While there has been significant research on the topic in recent years, little work has been done on mediation analysis when the intermediate variable (mediator) is a high-dimensional vector. In this work we introduce a novel method for mediation analysis in this setting called the principal directions of mediation (PDMs). We demonstrate the method using a functional magnetic resonance imaging (fMRI) study of thermal pain where we are interested in determining which brain locations mediate the relationship between the application of a thermal stimulus and self-reported pain.

Short bio: Martin Lindquist is a Professor of Biostatistics at Johns Hopkins University. His research focuses on mathematical and statistical problems relating to functional Magnetic Resonance Imaging (fMRI). Dr. Lindquist is actively involved in developing new analysis methods to enhance our ability to understand brain function using human neuroimaging. He has published over 70 articles, and serves on the editorial boards of several scientific journals both in statistics and neuroimaging. He is a fellow of the American Statistical Association.

Network Neuroscience: Going from Nodes to Edges

by prof. Olaf Sporns, Department of Psychological and Brain Sciences, Indiana University

When: Jan 28th, 2021 – 3:00 pm

Where: Zoom meeting. Recording available on Mediaspace

Abstract: It is said that complexity lies between order and disorder. In physiology, complexity issues are being considered with increased emphasis. Of crucial importance in the medical setting, pathological activity has been associated with low variability/complexity. In the case of the nervous system, it is well known that excessive synchronization is connected with pathologies such as epilepsy and Parkinson disease. However, brain rhythms and neural synchronization are also crucial for perception and cognition, so it is clear that either too much or not enough synchronization can lead to dysfunctional brain states.

Short bio: After receiving an undergraduate degree in biochemistry, Olaf Sporns earned a PhD in Neuroscience at Rockefeller University and conducted postdoctoral work at The Neurosciences Institute in New York and San Diego. Currently he is the Robert H. Shaffer Chair, a Distinguished Professor, and a Provost Professor in the Department of Psychological and Brain Sciences at Indiana University in Bloomington. Sporns holds adjunct appointments in the School of Informatics, Computing and Engineering, and in the School of Medicine. His main research area is theoretical and computational neuroscience, with a focus on complex brain networks. In addition to over 250 peer-reviewed publications he has written two books, “Networks of the Brain” and “Discovering the Human Connectome”. He is the Founding Editor of “Network Neuroscience”, a journal published by MIT Press. Sporns received a John Simon Guggenheim Memorial Fellowship in 2011, and the Patrick Suppes Prize in Psychology/Neuroscience, awarded by the American Philosophical Society, in 2017. He is a Fellow of the American Association for the Advancement of Science and the Society of Experimental Psychologists and of the Society of Experimental Psychologists.

Translational Neuroscience: From Network Theory To Personalized Medicine

by prof. Viktor Jirsa, Institut de Neurosciences, Aix-Marseille Universitè

When: June 18th, 2020 – 3:00 pm

Where: Zoom meeting

Abstract: Over the past decade we have demonstrated that the fusion of subject-specific structural information of the human brain with mathematical dynamic models allows building biologically realistic brain network models, which have a predictive value, beyond the explanatory power of each approach independently. Here we illustrate the workflow along the example of epilepsy: we reconstruct personalized connectivity matrices of human epileptic patients using Diffusion Tensor weighted Imaging (DTI).

Biophysical investigation of the molecular pathogenesis of CMT1X neuropathy

by prof. Mario Bortolozzi, Physics and Astronomy Dept., Padova

When: June 4th, 2020 – 3:00 pm

Where: Zoom meeting

Abstract: Mutations of connexin 32 (Cx32) protein cause the X-linked form of Charcot–Marie–Tooth disease (CMT1X), a demyelinating peripheral neuropathy for which there is no cure. A growing body of evidence indicates that ATP release through Cx32 hemichannels in Schwann cells could be critical for nerve myelination, but it is unknown if CMT1X mutations alter the physiological mechanism that controls Cx32 hemichannel opening and ATP release.

Our study uncovered a link between CMT1X and Cx32 hemichannel dysfunction, suggesting a candidate peptide for treating the disease caused by the R220X mutation of Cx32. The investigation was carried out by a combination of in vitro fluorescence optical microscopy combined with patch clamp and in silico numerical simulations.

The lecture will talk about visuomotor responses and place learning studies in flies made in our and other laboratories combining sophisticated quantitative behavioral techniques, fly genetic tools and optogenetics.

A Rational Framework for Studying Neurorehabilitation Interventions

by prof. Nick Ward, Institute of Neurology, UCL Queen Square

When: May 21th, 2020 – 2:30 pm

Where: Zoom meeting

Abstract: Stroke is the most common cause of neurological disability in the world. In the UK alone, there are more people living with the consequences of stroke than with dementia (1.2M vs 0.85M) with an estimated annual cost of £26B. Stroke is still considered a single incident disease with most resources targeted to the first few hours, days or weeks after onset.

Multitasking reveals impaired spatial awareness after stroke

by prof. Mario Bonato, Dep. of General Psychology, Padova

When: May 14th, 2020 – 3:00 pm

Where: Zoom meeting

Abstract: In everyday life contexts sometimes we manage to attend multiple sources of information without particular effort. Sometimes, however, performing two or more tasks together becomes very difficult, like for instance if we have to drive a car in a foggy day while paying attention to a debate on the radio. In these conditions our attention is loaded and we perform what is called “multitasking”.

Mesoscale connectivity changes after stroke and novel mouse models

by prof. Timothy Murphy, Dept. of Psychiatry, University of British Columbia

When: May 7th, 2020 – 3:00 pm

Where: Zoom meeting

Abstract: New approaches to real-time assessment and closed-loop feedback based on behavioral features or brain activity will be discussed in the lecture that are designed to optimize stroke recovery interventions in mice for insight into better approaches for human recovery.

The Primary Motor Cortex Seen by a Neurosurgeon: an Anatomical and Functional Appraisal

by Consultant Neurosurgeon PhD. Francesco Vergani, King’s College Hospital, London

When: February 20th, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Knowledge of the anatomical and functional relationship between brain tumours and surrounding cortical and subcortical structures is essential in neuro-oncology when planning overall treatment and surgical approach. This is particularly true for tumours in close relationship
to the primary motor cortex and the corticospinal tract (CST), where surgery carries the risk of inducing a permanent motor deficit.

The present review focuses on different aspects of the motor network.

Bridging Neuroscience and Neuroimaging Research to Clinical Practice in Anorexia Nervosa

by prof. Angela Favaro, Dept. of Neuroscience, University of Padova

When: February 6th, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Research in the field of neuroimaging, connectomics and neuropsychology is growing in the field of eating disorders.

In this presentation, I will review the recent advances of neuroscience research conducted by our group of research with a particular attention to those aspects that have direct or indirect clinical implications.

Functional Alignment of fMRI Exploiting Prior Information

by prof. Livio Finos, Dept. of Developmental Psychology and Socialisation, University of Padova

When: January 30th, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Multi-subject functional Magnetic Resonance Image (fMRI) studies are critical to test the validity of findings across subjects. However, the anatomical and functional structure varies across subjects, hence the image alignment is a fundamental step. One anatomical alignment is the Talairach Atlas, thus, it doesn’t account for functional topography. For that, Haxby et al. (2011) developed a functional approach called Hyperalignment, using sequential Procrustes orthogonal transformations. The inter-subject classification of functional response is improved. However, any constraint isn’t imposed to the transformation, losing results interpretability.

In this presentation, functional connectivity-related phenotypes associated with the risk for the disorders, their modulation by genetic variation and treatment will be discussed.

Imaging and Stimulating Adaptive Brain Plasticity

by prof. Heidi Johansen-Berg, Wellcome Centre for Integrative Neuroimaging, University of Oxford

When: January 23rd, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Animal studies show that the adult brain shows remarkable plasticity in response to learning or recovery from injury. Non-invasive brain imaging techniques can be used to detect systems-level structural and functional plasticity in the human brain.

This talk will focus on how brain imaging has allowed us to monitor healthy brains learning new motor skills, to assess how brains recover after damage, such as stroke, and how they adapt to change, such as limb amputation.

Dynamics of Brain networks in Psychosis: Implications for Diagnosis and Treatment

by prof. Fabio Sambataro, Dept. of Neuroscience, University of Padova

When: January 16th, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Psychoses are the most severe and devastating psychiatric disorders that cut through the classical nosological categories and include schizophrenia spectrum disorders as well as affective disorders. Genetic and environmental factors have been associated with their etiology, but their pathophysiology is still unknown. Neuroimaging studies have investigated structural and functional changes associated with the risk for these disorders along with their treatment response.

In this presentation, functional connectivity-related phenotypes associated with the risk for the disorders, their modulation by genetic variation and treatment will be discussed.

A Note on the Use of Topic Modeling and Deep Learning to Advance Information Retrieval

by prof. Massimo Melucci, Dept. of Information Engineering, University of Padova

When: January 9th, 2020 – 3:00 pm

Where: VIMM Seminar Hall

Abstract: Information Retrieval (IR) is the complex of theories, models, and technologies aiming to retrieve relevant information to user’s information needs. IR has recently made significant advances in understanding the content of multimedia documents and user queries.
In this talk, I’ll illustrate some noticeable advances, in particular, how topic modeling helps understand content and how the use of deep learning helps overcome some obstacles.
