Summary of electrophysiological properties of inhibitory and noninhibitory neurons in the INC and the PHN
V+ INC | V+ PHN | V- INC | D- PHN | ||
---|---|---|---|---|---|
Input capacitance (pF) | 56.0 ± 21.7** | 31.5 ± 17.6 | 54.7 ± 23.8* | 47.6 ± 32.5 | |
Input resistance (MΩ) | 423.1 ± 187.5** | 662.9 ± 296.4 | 358.0 ± 180.1** | 572.9 ± 335.3 | |
Spike amplitude (mV) | 72.3 ± 7.8 | 74.6 ± 7.0 | 69.7 ± 8.4** | 76.9 ± 8.9 | |
Spike half-width (ms) | 0.398 ± 0.11** | 0.441 ± 0.11 | 0.39 ± 0.13** | 0.54 ± 0.14 | |
AHP amplitude (mV) | 28.7 ± 6.1** | 32.1 ± 4.9 | 26.4 ± 5.5** | 29.1 ± 5.0 | |
Spontaneous firing rate (spikes/s) | 10.4 ± 7.2 | 9.2 ± 4.5 | 6.1 ± 5.8 | 7.1 ± 4.3 | |
CV of the interspike interval (%) | 17.2 ± 29.3* | 8.8 ± 12.9 | 16.3 ± 19.5** | 8.3 ± 13.5 |
The analyses were performed on data collected from 70 V+ and 70 V- PHN neurons and 55 V+ and 55 V- INC neurons. The CVs of the interspike interval were analyzed in the neurons that fired spontaneously (52 V+ INC, 68 V+ PHN, 40 V- INC, and 67 D- PHN). Asterisks indicate significant differences between V+ INC and V+ PHN or between V- INC and D- PHN. *p < 0.05; **p < 0.01.
