- Percentage of Fluorogold (FG)-immunoreactive neurons (Mean ± SE) within the ipsilateral and the contralateral ventral tegmental area to the FG injection site in the three injection site groups using immunohistochemistry (IH) or immunofluorescence (IF) techniques. Cg1: cingular cortex (n = 4 animals); MO: medial orbital cortex (n = 4 animals); PL: prelimbic cortex (n = 10 animals). Percentages were calculated from the FG-immunolabeled neurons counted in 8 vibratome sections per animal in IH experiments and in 5 vibratome sections per animal in IF experiments.
