Representation, Coding and Computation in Neural Circuits

source: Simons Institute      2018年2月12日
The aim of this workshop is to shed light, at the level of cortical circuits, on issues of representation and coding such as sparsity and high-dimensionality, spikes and coding capacity in the presence of noise. It will also address questions related to how neurons compute: the role of dendritic nonlinearities and clustered plasticity, recurrent circuits, excitatory-inhibitory balance and models of cooperative computation (as opposed to single neuron computation).
