Around the complex interplay between organization, heterogeneity and collective dynamics of neuronal networks.
Jonathan Touboul, College de France- INRIA

Increasing biological evidence suggest that topology and structure of cortical areas subtend perception and function. I will present a model of the development of the nervous system based on first principles, and show how this led us to interpret robustness of boundary formation between distinct cortical areas as a general property of a new class of reaction-diffusion systems in heterogeneous media. I will then show how sensitively the activity of stochastic neuronal networks depends on spatial organization, noise and heterogeneity, with a particular focus on the emergence of synchronization between neurons and, in an uncluttered and simple network model, in hipster's fashion codes.
