Abstract
Event Abstract Back to Event A computational model of the mouse C2 barrel cortex column Christian Tomm1*, Michael Avermann2, Carl Petersen2 and Wulfram Gerstner1 1 EPFL-LCN, Switzerland 2 EPFL, LSENS, Switzerland In continuation of work done in [Lefort09], we are presenting a model of the mouse C2 barrel cortex column. Our model contains six cortical layers, each consisting of heterogeneous populations of excitatory and inhibitory neurons. To simulate these neurons we use the Adex neuron model [Gerstner09] fitted to experimental datasets collected through electrophysiological recordings. Connectivity probabilities and strengths are drawn from statistics that were fitted to a range of biological observations. Our work aims to understand how spikes are generated and how information is transmitted within a network. Specifically, we are looking at the neural dynamics of our model and compare them to biological recordings that show differences in spike initiation between excitatory and inhibitory populations. Advancing from abstract networks, our goal is to explain differences in network behaviour with respect to the network connectivity and structure.
