(A and C) Representative confocal photomicrophotographs of the cFos staining after each treatment in coronal sections at 1.9 mm of the interaural line in the ARC and −3.78 mm of the interaural line in the NTS ; (B and D) Average of cFos-positive nuclei per section after the different treatments between 2.2/1.6 mm of the interaural line for the ARC and between −3.78/−3.98 mm of the interaural line for the NTS. Data represent mean±SEM. ***P<0.001 vs saline, *P<0.05 vs saline, #P<0.05 vs ghr. Scale bar represents 100 µm in the ARC and 50 µm in the NTS. 3V: third ventricle, ME: median eminence, DMH: Dorsomedial Hypothalamic nucleus, VMH: Ventromedial Hypothalamic nucleus, ARC: Arcuate nucleus, NTS: Nucleus Tractus Solitarius, AP: Area Postrema, 10N: Dorsal Motor Nucleus of Vagus, cc: central canal.
