Statistical analysis of spike trains in neuronal networks

International audienceRecent advances in multi-electrodes array acquisition has made it possible to record the activity ofup to several hundreds of neurons at the same time and to register their collective activity (spiketrains). This opens up new perspectives in understanding how a neuronal network encodes theresponse to a stimulus, and what a spike train tells up about the network structure and nonlineardynamics. For this, one has to develop statistical models properly handling the spatio-temporalaspects of spike trains, including memory effects. In this talk, I will review several such statisticalmodels, including Maximum Entropy Models, Generalized Linear Model or neuromimetic models,and their application for the analysis of retina data
