Schematic distribution of Fos+ (grey dots), MCH+ (black dots) and MCH+/Fos+ (red dots) neurons on two coronal hemi-sections of the hypothalamus in a representative animal for PS-Control (A1, A2), PS-Deprivation (B1, B2) and PS-Recovery (C1, C2) conditions. Note the very large number of MCH+/Fos+ cells specifically in the PSR condition. Abbreviations: Arc, arcuate nucleus; DA, dorsal hypothalamic area; DMH, dorso-medial hypothalamic area; f, fornix; ic, internal capsule; LHA, lateral hypothalamic area; mt, mammillothalamic tract; opt, optic tract; PeF, perifornical area; VMH, ventro-medial hypothalamic area; ZI, zona incerta.
