  1. 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.
