Abstract of the workshop

New advances in mathematical and computational neurosciences require the development of mathematical tools able to explain the dynamical evolution observed at different spatiotemporal scales. Our idea is to focus on the specific issue of meso/macroscopic dynamical behaviors in neural systems, given their relevance for population coding and computation. This workshop aims at discussing some of the most recent analytical techniques and mathematical tools used to derive the evolution of neural populations and its emergent dynamics, with the hope of understanding how features of meso/macroscopic systems such as local dynamics, heterogeneity, noise and topology shape their response. With this workshop we expect to bridge the gap between models and data and to further shed light on the inter-relation between structure, dynamics and function of the brain circuitry by studying the transitions between different collective states.
