| Parameter | Pyramidal neurons | SST interneurons | PV interneurons |
|---|---|---|---|
| Average membrane potential (mV) | -74.1 ± 0.9 (n = 21) | -63.3 ± 1.6 (n = 20) | -66.3 ± 1.8 (n = 11) |
| Resting membrane potential (mV) | -78.0 ± 0.7 (n = 21) | -65.7 ± 1.7 (n = 20) | -72.2 ± 1.5 (n = 11) |
| Input resistance (MΩ) | 51.1 ± 2.9 (n = 21) | 97.9 ± 6.2 (n = 20) | 43.9 ± 7.8 (n = 11) |
| AP half-width (ms) | 1.65 ± 0.07 (n = 20) | 1.02 ± 0.06 (n = 20) | 0.56 ± 0.04 (n = 11) |
| AP threshold (mV) | -40.9 ± 1.3 (n = 20) | -41.4 ± 1.0 (n = 20) | -46.4 ± 0.9 (n = 11) |
| Spontaneous spiking rate (Hz) | 0.03 ± 0.01 (n = 19) | 1.3 ± 0.3 (n = 14) | 9.3 ± 3.1 (n = 11) |
| Maximum spiking rate* (Hz) | 45.5 ± 5.2 (n = 18) | 75.7 ± 9.0 (n = 19) | 163.3 ± 20.0 (n = 11) |

Data are given as mean ± SEM.

The dataset for analyzing electrophysiological properties is 21 Exc neurons, 20 SST neurons, and 11 PV neurons. The smaller sample size of some parameters for pyramidal neurons and SST interneurons is due to the lack of APs in few recordings.

↵*Maximum spiking rates are underestimates of the true maximum rates.
