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.
