| : IS cells had an average input resistance of 127.7 ± 7.2 MΩ and a time constant of 12.2 ± 1.0 msec (n = 21 cells). Their spikes had an average amplitude of 67.4 ± 1.9 mV, a half-width of 0.80 ± 0.05 msec, and were followed by an AHP with an amplitude of 13.5 ± 0.5 mV and a decay of 55.8 ± 5.2 msec (Fig. 2A,E). The minimum value of the AHP occurred on average 7.1 ± 0.8 msec after the spike peak (Fig. 2E). Figure 2 compares the firing pattern and the properties of individual spikes in IS (Fig. 2 A,C,E) and in FS (Fig. 2B,D,F) cells. | |||||||
