title: Mapping of alpha-melanocyte-stimulating hormone-like immunoreactivity in the cat brainstem.
abstract: The distribution of alpha-melanocyte-stimulating hormone-like immunoreactive structures was studied in the brainstem of the cat using an indirect immunoperoxidase technique. Immunoreactivity was observed in several brainstem nuclei of the cat in which no immunoreactivity had been previously reported. Immunoreactive fibres were observed in the following; the inferior central nucleus; the pontine gray nuclei; the Kölliker-Fuse nucleus; the motor trigeminal nucleus, the anteroventral cochlear nucleus; the abducens nucleus; the retrofacial nucleus; the superior, lateral, inferior, and medial vestibular nuclei; the lateral nucleus of the superior olive; the external cuneate nucleus; the nucleus of the trapezoid body; the postpyramidal nucleus of the raphe; the medial accessory inferior olive; the dorsal accessory nucleus of the inferior olive; the nucleus ambiguus; the principal nucleus of the inferior olive; the preolivary nucleus; the nucleus ruber; the substantia nigra; and in the area postrema. Our results point to a more widespread distribution of alpha-melanocyte-stimulating hormone-like immunoreactive structures in the cat brainstem than that reported in previous studies carried out in the same region of the cat, rat and humans.
