Schematic drawings illustrate the brain regions where the refeeding-activated (c-Fos-positive, black) neurons that projects to the CEA (CTB-immunoreactive perikarya, brown) are located. These double-labeled neurons are present in the prelimbic area (PrL; A, B), agranular insular area, posterior part (AIp; C, D), visceral area (VISC; D), supplementary somatosensory area (SSs; D, F), primary somatosensory cortex, barrel field (SSp-bfd; D), bed nuclei of the stria terminalis (BST; E, G), perifornical nucleus (PeF; H, I), piriform area (PIR; J), lateral hypothalamic area (LH; K), nucleus of the solitary tract (NTS; L), ventrolateral division of the periaqueductal gray (PAGvl; M, P), paraventricular thalamic nucleus (PVT; N), parasubthalamic nucleus (PSTN; N, Q), arcuate hypothalamic nucleus (ARC; N, R), PBN (O, S). Representative images illustrate the distribution of the double labeled neurons in these areas. Arrows indicate examples of double-labeled neurons. Scale bar = 500μm in the schematic drawing and 20μm in the photomicrograph.
