Spatial integration in the dendrites. In these simulations on the Z+ PC model, type II BPRs were elicited by 500 Hz—10 spikes pf bursts in dendritic sectors I and II and SC synapses were activated by 130 Hz—three spikes trains in the same sectors. The number of active pf synapse was either 50 or 100. (A) The raster plots and PSTH show model responses when sectors I and II are activate alone or together. (B) The histograms show the amplitude of PSTH peak and the depth and duration of the pause in the different cases.
