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: Ramon Guevara is a physicist at the Department of Physics of the University of Padova. His main interest lies in the interface between biophysics and neuroscience. He has been a research fellow at several institutions, universities and hospitals around the world, including the University Paris Descartes, the Hospital for Sick Children in Toronto, the University of British Columbia in Vancouver and the neuroimage center Neurospin, at Saclay, France. His research focuses on the coordination of neural activity, both in the normal and the pathological brain, and in particular on the search of principles underlying synchronization phenomena in the brain, and their physiological and cognitive implications.
