Figure 6From: Hypocretin1/orexinA-immunoreactive axons form few synaptic contacts on rat ventral tegmental area neurons that project to the medial prefrontal cortexBar graph showing the percentage distribution of contact types (apposition [App] or asymmetric synapse [Syn]) or absence of contact (No cont) between Hcrt1/OxA-containing unmyelinated axons (Ax) or boutons (B) with ventral tegmental area dendrites that are unlabeled (un) or Fluorogold-labeled (FG). Percentages (mean ± SE) were obtained from 14 vibratome sections of 6 rats, representing the distribution of a total number of 2,174 Hcrt1/OxA-immunolabeled axons with respect to their contacts with dendrites within the ventral tegmental area.Back to article page
