title: [Histamine-immunoreactive neurons in the hypothalamus of cats].
abstract: The localization of histaminergic neurons in the cat brain was determined immunohistochemically with an antibody against histamine. We found that histamine-immunoreactive neurons are observed exclusively in the posterior hypothalamus of colchicine treated cats. The larger group of neurons was found in the ventrolateral part of the posterior hypothalamus, including the tuberomammillary nucleus. Histamine-positive neurons were also observed in the supramammillary area and adjacent posterior hypothalamic area, as well as in the peri- and premammillary regions. In addition, numerous histamine immunoreactive fibers were detected, not only in the posterior hypothalamus, but also in other brain areas, such as the preoptic area of the anterior hypothalamus.
