Abstract: Neurons in the brain are wired into adaptive networks that exhibit a range of collective dynamics. Oscillations, for example, are paradigmatic synchronous patterns of neural activity with a defined temporal scale. Neuronal avalanches, in contrast, are scale-free cascades of neural activity, often considered as evidence of brain tuning to criticality. While models have been developed to account for oscillations or avalanches separately, they typically do not explain both phenomena, are too complex to analyze analytically, or intractable to infer from data rigorously.

Abstract: Understanding language is a complex task that neurologically intact people seem to perform very easily. To achieve this, our brain does not only passively process incoming stimuli, but also proactively predicts upcoming information to facilitate processing. In this talk I will present past and ongoing studies that investigate some aspects of such predictive processes, by using electroencephalography with both typically developed adults, and people with atypical development.

Abstract: There is increasing experimental evidence that the activity of single cortical neurons can make a difference to the brain. One particularly striking example is that rats can be trained to respond to the stimulation of a single cell in the barrel cortex. It is not clear how this finding can be reconciled with the usual textbook view that only large neuronal populations can reliably encode information, as is often argued on the basis of the large noise and chaotic dynamics of cortical networks.

Abstract: In neuroscience, the structural connectivity matrix of synaptic weights between neurons is one of the critical factors determining the overall function of a network of neurons. The mechanisms of signal transduction have been intensively studied at different time and spatial scales and at both the cellular and molecular level. While a better understanding and knowledge of some basic processes of information handling by neurons has been achieved, little is known about the organization and function of complex neuronal networks.

Abstract: Functional MRI has been advanced by improvements in acquisition, processing, and our understanding of the neurovascular response, leading to new insights, applications, and avenues of research. In this lecture, the challenges and opportunities in working with fMRI at its limits of resolution,
sensitivity, and interpretability are described. Several examples of ultra-high resolution mapping of cortical layer activity and connectivity are shown, opening up the capability of fMRI to map directional connectivity and functional hierarchy. Also presented are some of my lab’s recent work on tracking ongoing cognition, assessing vigilance, and reducing physiologic noise – all through the integration of novel pulse sequences, paradigms, and processing methods.
