Fig. 6 Fig. 6. Immunofluorescent microphotographs of selected transverse sections showing colocalization of β2-ΑRs on GAD67 expressing cells, across the SDM network. (A-C) Double immunofluorescence showing high degree of colocalization between β2-ΑRs (green) and GAD67 (red) in (A) ventral nucleus of the ventral telencephalic area (Vv), (B) medial zone of the dorsal telencephalic area (Dm), (C) parvocellular preoptic nucleus, anterior part (PPa). Arrows indicate examples of colocalization, arrowheads point to single positive cells. Microphotographic images are representative of both control (B, C) and MK–801-treated (A) fish. Scale bar: 0,05 mm. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
