Projects

My project is focused on understanding how the cellular and connectivity properties of neural assemblies shape the collective dynamics emerging at the network level. Together with the experimental team of T. Fellin (IIT Genova), we are particularly interested in the role of the various inhibitory subnetworks in shaping the dynamical patterns of spontaneous and sensory-evoked activity in mammalian neocortex. I investigate this question using numerical simulations of neural network dynamics and its associated mathematical reductions (relying on techniques coming from the field of statistical physics and dynamical systems theory). Back-and-forth between the multimodal recordings of the Fellin team and our reductionist theoretical approach, this joint effort aims at providing a comprehensive picture for the role of circuit features in shaping neocortical processing.
