Figure 2.

Electrophysiological and anatomical heterogeneity in the GP is replicated in the model DB. A, Electrophysiological heterogeneity in the GP is shown by two example neurons (s25 and s61) that exhibit distinct characteristics such as the occurrence of a voltage “sag” with hyperpolarizing current stimulus and different spontaneous firing rates. B, C, Histograms of electrophysiological measurements from the physiology neuron DB (B) compared with the histograms of measurements from the model DB (C). The bins representing models with no spontaneous spiking were omitted for clarity in the rate and rebound histograms. spont. rate, Spontaneous rate; AP amp., AP amplitude; SFA, spike frequency accommodation.
