- The distribution of putative histaminergic neurons in the brain of a teleost, the three-spined stickleback, was investigated by means of immunocytochemistry using specific antibodies against histamine (HA), and conventional microscopy as well as confocal laser scanning microscopy. Histamine-immunoreactive (HAir) neurons form discrete populations ventral to the nucleus of the posterior recess (NRP) and in the nucleus saccus vasculosus (NSV), which belong to the periventricular hypothalamic nuclei. The neuronal somata are subependymally located, and do not possess apical neurites contacting the cerebrospinal fluid. They give rise to both long-range and local axonal projections. The local projections give rise to a field of dense punctate immunoreaction dorsal to the NRP and lateral to the NSV. Long-range projections are comprised of ascending projections to the thalamus, habenula, preoptic area and dorsal telencephalon; and descending projections via the posterior tuberal nucleus, ventrally to the nucleus interpeduncularis, and dorsally into the central gray. HAir neurons occur together with serotoninergic cerebrospinal fluid-contacting (CSFc) neurons in the NRP, and with tyrosine hydroxylase-immunoreactive (THir) neurons in the NSV. Although HAir elements occur together with THir ones in many brain areas, direct contacts between the two neurotransmitter systems are rare. The putative histaminergic neurons in the brain of the three-spined stickleback constitute a very discrete neuronal system, with a major projection area in the dorsal telencephalon in a region which is considered homologous with the dorsal pallium of land vertebrates.
