Our goal is to understand how collective neuronal activity is organized and how this organization sub-serves coding in the brain. But how to expose simple coding principles from the multi-scale complexity of neuronal systems? We are motivated by the acknowledgement that brains and neuronal coding schemes are products of evolution and can be flashed out by viewing them in an evolutionary context, by using comparative approaches over diverse species and by choosing optimal models systems. Specifically, we study the brains of reptiles which are the closest to stem amniotes - the first animals that completed the transition to life on land and the first to develop a layered cerebral cortex.
Tools. We employ a wide set of techniques to study the hitherto under-explored reptilian brain: We use large-scale (thousands of electrodes) extra-cellular electrophysiology and intra-cellular electrophysiology to study circuits both ex-vivo and in-vivo. We develop data analysis approaches to deal with the overgrowing richness of our data sets. We couple our experiments with quantitative behavioral analysis to place brain dynamics in context. We build computational models to test ideas and develop theories.
