Fig. 2.
Delayed bursting in the model endopiriform nucleus. Traces in Upper are somatic potentials of two model multipolar neurons (of 500); the trace in Lower is the inverted average of multipolar somata, approximating a field. The triangle marks a 5-ms 0.6-nA current pulse to 50 of the multipolar neurons, which were randomly chosen. The density of gNa(P) was 0.001 × the density of fast transient gNa. Compare with figure 2 of ref. 7, which illustrates activity in a kindled endopiriform nucleus in vitro.
