Figure 6

Main hypothalamic pathways involved in ghrelin-induced food intake. Arrows and lines indicate stimulation and inhibition, respectively. AGRP: agouti-related protein; ARC: arcuate nucleus; CART: cocaine- and amphetamine-regulated transcript; CRF: corticotrophin-releasing factor; LHA: lateral hypothalamic area; NPY: neuropeptide Y; POMC: proopiomelanocortin; and PVN: paraventricular nucleus.
