Fig. 8.

The colocalization relationship between the retrogradely labeled FG, which was injected into the VA-VL, and NOS and/or SOM in the EPN. The pseudocolor images in (a) and Inset consist of NOS (red), SOM (green), and FG (Blue) immunoreactivities, which are shown separately in (b–d). NOS/FG double-positive neurons are shown by arrows, whereas SOM/FG double-positive neurons are shown by arrowheads. EP, entopeduncular nucleus; GP, globus pallidus; Hy, hypothalamus; IC, internal capsule; Th, thalamus. The scale bars for images (a) and Inset are 100 and 500 µm, respectively
