Appositional contacts and synapses established by Hcrt1/OxA profiles in the ventral tegmental area
| Hcrt1/OxA axonal profile type | Appositional contacts | Synapses (asymmetric) | Total | ||
|---|---|---|---|---|---|
| FG | Unlabeled | FG | Unlabeled | ||
| Unmyelinated axon (n = 1558) | 42 | 96 | 2 | 5 | 145 |
| Varicosity (n = 579) | 20 | 55 | 4 | 11 | 90 |
| Axon terminal (n = 37) | 5 | 0 | 3 | 4 | 12 |
| Total | 67 | 151 | 9 | 20 | 247 |
Raw numbers of appositional contacts and synapses made by Hcrt1/OxA axonal profiles in the ventral tegmental area with either Fluorogold (FG)-labeled or unlabeled dendrites. Data were collected from 14 vibratome sections processed for dual labeling (Hcrt1/OxA and FG) in 6 rats that had been injected with FG in the prelimbic sector of the medial prefrontal cortex.
