Table. Response characteristics of neurons in dorsal column nuclei to high frequency of SCS (90% MT, 50 Hz, 0.2 ms, 10 s).
| Responses to SCS | n | Spontaneous activity (imp/s) | Latency (s) | Excitatory responses (imp/s) | Inhibitory responses (imp/s) | Duration of responses (s) |
|---|---|---|---|---|---|---|
| Excitatory | 30 | 9.1±1.7 | 0.5±0.1 | 53.1±7.6 | N/A | 17.3±1.3 |
| Inhibitory | 24 | 16.5±1.9* | 0.5±0.2 | N/A | 10.3±1.1 | 17.5±2.0 |
