Made by @agreyr

Hypothalamus

Complex effects on ingestive behavior

Regulation of energy balance; regulation of metabolism; motor behaviors

Depends critically on interconnections with other brain regions

Two regions of hypothalamus implicated

Ventromedial hypothalamus (VMH) and Lateral hypothalamus (LH)

Two types of peptide hormones

Satiety peptides and Hunger peptides

Satiety peptides

Decreases appetite

Cholecystokinin (CCK), α-MSH, Somatostatin, Leptin, PYY_3-36, GLP-1

Hunger peptides

Increase appetite

Neuropeptide Y, Galanin, Orexin-A, Ghrelin
