RNA in situ hybridization on adult brain sections showing expression of oxt and crx expressing cells. (a,a′) Coronal sections of brain showing expression of oxt in the anterior parvocellular preoptic nucleus (PPa) in control and 5mGy/(D5) irradiated fish. The black rectangle represents the area for the higher magnification images. (b,b′) Expression of crx in the PPa in the control and after irradiation at 5 mGy/h(D5). The black arrow heads delineate the ventricular zone (VZ) in the medial ventricular zone of the PPa and the white asterisk represents the location of VZ progenitors where ectopic expression is detected. Scale bar = 100 µm. The scheme at the top represents the location of the coronal sections in the brain.
