Homosynaptic paired-pulse facilitation/depression in the hippocampal–PFC and MD–PFC pathways
| ISI | Mean (SEM) FF-evoked firing probabilities | Mean (SEM) MD-evoked firing probabilities | ||
|---|---|---|---|---|
| Conditioning pulse | Test pulse | Conditioning pulse | Test pulse | |
| 25 msec | 46.4 (3.4) | 53 (10.7) | 48 (6.1) | 44.4 (8.8) |
| 50 msec | 40.6 (5.8) | 60 (6.3)* | 50 (6.1) | 42.2 (9.3) |
