Colocalization of FG, GAD-67 and 5-HT_2CR in the VTA.

<p>Photomicrographs display FG- [blue, A], GAD-67- [red, B] and 5-HT_2CR-labeling [green, C] in series of five sequential images (from left to right) captured using a confocal microscope in the VTA of a rat injected with FG in the NAc shell. Photomicrographs represent images captured at a distance of 1.0 µm apart through the thickness of the brain section. [D] Overlay of images in A-C shows colocalization of GAD-67- and 5-HT_2CR-IR in a FG-labeled cell in the VTA. Scale bars = 10 µm.
