Simulation of multilayer networks. a Dot rasters of spikes showing simulations of a purely feedforward network composed of only excitatory neurons (480 neurons; see Methods for a detailed description of the network and parameters). All neurons of a single trial are shown in the dot raster (top) and 30 trials are compiled to plot the average firing rate (bottom). b Same network as in a but with additional recurrent connections between and within layers. c Same network as in b with inhibitory neurons (120 inhibitory neurons, i.e. 20%, presented as light dots in the spike raster). d Same network as in c but with NMDA-mediated synaptic current
