Figure 4: Coarse-grained whole-brain mapping of neural inputs to MCH cells.
From: Awake dynamics and brain-wide direct inputs of hypothalamic MCH and orexin networks
(a) Scheme showing relative contributions of seven large-scale areas to MCH cell input. The area of each circle represents the proportion of total whole-brain inputs (see the Results for details). Area names are based on the Allen Atlas: CNU, cerebral nuclei; CTX, cortex; HY, hypothalamus; MB, midbrain; MY, medulla; P, pons; TH, thalamus. (b) Examples of morphologies of neurons sending direct inputs to MCH neurons in different brain regions. The numbers above slice schematics correspond to image numbers in the Allen Atlas. Scale bars, 200 μm. Representative examples of n=6 brains. ac, anterior commissure; AQ, cerebral aqueduct; BST, bed nuclei of the stria terminalis; cc, corpus callosum; CEA, central amygdalar nucleus; cpd, cerebal peduncle; dscp, superior cerebellar peduncle decussation; DMH, dorsomedial nucleus of the hypothalamus; DR, dorsal nucleus raphe; ENT, entorhinal area; fx, columns of the fornix; int, internal capsule; LHA, lateral hypothalamic area; LSc, lateral septal nucleus, caudal part; LSr, lateral septal nucleus, rostral part; mlf, medial longitudinal fascicle; mtt, mammilothalmic tract; opt, optic tract; PAG, periaqueductal grey; PVH, paraventricular hypothalamic nucleus; SON, supraoptic nucleus; SSs, supplemental somatosensory area; SUBv, subiculum, ventral part; V3, third ventricle; VL, lateral ventricle.
