Sender Network Activity

(A and B) Spike raster showing 100 ms of activity in the sender network in the asynchronous (A) and oscillating (B) states. (A1 and B1) principal cell spike raster. (A2 and B2) Interneuron spike raster. (A3 and B3) Average firing rate for the principal cells (blue) and interneurons (green). (A4 and B4) Membrane potential of sample principal cell. (A5 and B5) Synaptic currents in sample principal cell (excitatory: blue; inhibitory: green; net current: red).

(C) Average firing rate of a subpopulation of 400 principal cells over a 50 ms window in the asynchronous (C1) and oscillatory (C2) states. Activity was sampled from the areas indicated by colored outlines in the spike rasters (A1 and B1).

(D) Fourier transforms of the subpopulation firing rates shown in (C). Arrows illustrate the 0 Hz (average firing rate) and 41 Hz (gamma amplitude) measurements used in later analysis.
