Fig. 8. Behavior of fast-spiking Interneuron model as αsynis increased, corresponding to an increase in the rate at which GABAAchannels open. The membrane potential for an individual neuron is shown in the left-hand column. The average membrane potential from all 100 neurons in the simulation is shown in the right-hand column and is the analog of the electroencephalograph for the model. Simulations are shown for αsynequal to 1 · ms−1(A ) and 6 · ms−1(B ). Note how increasing αsynleads to more synchronous behavior. Further increases in αsyndo not lead to any fundamentally different behavior from that shown here.
