The sites of origin of a-melanocyte-stimulating hormone-containing axonal components in the lateral area of the midbrain periaqueductal gray of the rat.
The sites of origin of alpha-melanocyte-stimulating hormone (alpha-MSH)-containing axonal components in the lateral area of the midbrain periaqueductal gray (PAG) were studied in the rat by the retrograde tracing method of horseradish peroxidase, combined with the immunocytochemical technique. The results indicated that alpha-MSH-containing axonal components in the PAG arose not only from the arcuate nucleus of the hypothalamus but also from the ventral zona incerta, the periventricular, perifornical and lateral hypothalamic regions.
