LTM | 6 | -58.3 ± 3.5 | 34.1 ± 4.5 | R (4), B (2) | 2.6 ± 0.3 |
WDR | 3 | -55.1 ± 4.9 | 36.2 ± 3.1 | R (1), B (2) | 4.5 ± 1.2 |

- LTM, Low- threshold mechanoreceptive; WDR, wide-dynamic range; NS, nociceptive specific. Resting membrane potential (RMP), the values reported refers to that taken during the hyperpolarized period (down-state) between ongoing spontaneous depolarization (up-state). The input resistance (Rin) was calculated by injecting negative current into the soma and determing the voltage drop after current injection. Firing pattern of spontaneous activity: R, Regular pattern; B, bursting pattern. Values in parentheses are number of neurons.
