Fig. 5. Behavior of network model of the reticular nucleus of the thalamus, described in Appendix C, as βsynis decreased, corresponding to a prolongation in the time that GABAAchannels remain open. The membrane potential for a single neuron within the network is shown in the left hand-hand column. The average of the membrane potential from all 100 neurons in the simulation is shown in the middle column and is the analog of the electroencephalograph for the model. A raster plot for all 100 neurons is shown in the right-hand column, and was generated by indicating when the membrane potential of a given neuron exceeds -55 mV. Simulations are shown for βsynequal to 0.08 (A ), 0.04 (B ), 0.01 (C ), and 0.005 · ms−1(D ).
