Coexistence of cell assemblies and STDP

Abstract

We implement a model of leaky-integrate-and fire neurons with conductance-based synapses. Neurons are structurally coupled in terms of an ideal cell assembly. Synaptic changes occur through parameterized spike timing-dependent plasticity rules which allows us to investigate the question whether cell assemblies can survive or even be strengthed by such common learning rules. It turns out that for different delays there are parameter settings which support cell assembly structures and others which do not. © 2009 Springer Berlin Heidelberg.
