Electrophysiological properties of LTS+ and LTS−
| LTS+ neurons | LTS− neurons | |
|---|---|---|
| Membrane potential (mV) | −57.0 ± 0.96 (26) | −57.4 ± 1.42 (18) |
| Action potential amplitude (mV) | 71.4 ± 1.67 (26)* | 77.1 ± 1.83 (18)* |
| Action potential duration (msec) | 1.52 ± 0.09 (26)2_a | 1.19 ± 0.08 (18)2_a |
| Input resistance (MΩ) | 66.0 ± 6.42 (26) | 57.3 ± 5.49 (18) |
*p < 0.05 (Student’s t test).
↵F2_a The distributions of this parameter did not meet the criteria for normal distribution and were compared with the Mann–Whitney rank sum test, being the difference significant (p < 0.02; medians 1.40 msec, LTS+ and 1.10 msec, LTS−).
The amplitude of the action potentials was measured from the threshold level, and the duration was measured at half-amplitude. The input resistance was measured from the response to small (−0.1 nA) hyperpolarizing current pulses. Values are given as mean ± SEM (n).
