Line drawings adapted from the Paxinos and Watson rat brain atlas (34) showing the location of areas analyzed for Fos immunoreactivity. The corresponding atlas plate is listed in the top center, and the distance from bregma is at the bottom left of each drawing. Analyzed regions (shaded areas) were outlined with the aid of Nissl-stained sections. Scale bar (upper left drawing), 500 μm (applies to all). 3V, Third ventricle; ac, anterior commissure; AHA, anterior hypothalamic area; ARC, arcuate nucleus; DMN, dorsomedial nucleus; f, fornix; LH, lateral hypothalamus; LPO, lateral preoptic area; LV, lateral ventricle; ME, median eminence; MPN, medial preoptic nucleus; MPO, medial preoptic area; MS, medial septal nucleus; mt, mammillothalamic tract; oc, optic chiasm; ot, optic tract; POA, preoptic area; PS, parastrial nucleus; PVN, paraventricular nucleus; RCh, retrochiasmatic area; SCH, suprachiasmatic nucleus; SHy, septohypothalamic nucleus; VLPO, ventrolateral preoptic area; VMN, ventromedial nucleus.
