Interstimulus interval (sec) | off cell discharge (before 2nd pulse relative to before 1st pulse) | on cell discharge (before 2nd pulse relative to before 1st pulse) | Predicted motor reaction (to 2nd pulse relative to 1st pulse) |
---|---|---|---|
0.8 | ↓↓ | ↑↑ | ++ |
2.0 | ↓↓ | ↑ | + |
10.0 | ↓ | ↑ | + |
Magnitude of facilitation is entirely dependent on oncell discharge.
