"The ARC contains a high density of neurons that produce orexigenic peptides such as
neuropeptide Y (NPY), opioids, β-endorphin (β-END), galanin (GAL) and glutamate. α-
melanophore-stimulating hormone (α-MSH), an anorexigenic peptide, is also co-produced with β-END in ARC."

Thank you andedammen, that is exactly what I was thinking too.

j/k, the paper definetely has some useful info
