    Notes: Summary Changes occurring in serotonin neurons during hyperthermia and hyperthermia-induced convulsions were examined by quantiative immunohistochemistry. A marked increase in serotonin immunoreactivity was observed at the rostral and intermediate levels of the neostriatum of mice kept at high temperatures with no convulsions, and a significant reduction in serotonin immunoreactivity was verified throughout the neostiatum of mice which had hyperthermia-induced seizures. These results suggest that serotonin neurons change significantly during thermal stress and seizures, and that regional analysis is essential for an understanding of the role of serotonin neurons.

    Notes: Summary Changes occurring in serotonin neurons during hyperthermia-induced convulsions were examined by means of a modified immunohistochemical method. All mice (8–12 weeks of age) exposed to the temperature of 50°C had convulsions, showing a generalized tonic and/or clonic pattern. Immediately after the convulsions, the animals were perfused transcardially with a fixative. A significant reduction in serotonin immunoreactivity was observed in the neostratum (caudate-putamen complex) of the mice which had hyperthermia-induced seizures, while the serotonin immunoreactivity remained unchanged in the neocortex and paleostriatum. These results suggest that serotonin may be an important mediator in the mechanism of hyperthermia-induced convulsions or that the susceptibility of serotonin neurons to a convulsive state is greatest in the neostriatum.

    Immunohistochemical demonstration of serotonin-containing nerve fibers in the hypothalamus of the monkey, Macaca fuscata (1984)

    Notes: Summary The distributional pattern of serotonin-containing nerve fibers in the hypothalamus of the monkey (Macaca fuscata) was analyzed with the use of the peroxidaseantiperoxidase method in conjunction with a highly sensitive and specific anti-serotonin serum. The highest concentrations of serotonin-immunoreactive varicose fibers were found in the nucleus praeopticus medialis, nucleus ventromedialis hypothalami, and the complex of mammillary nuclei (nucleus praemamillaris, supramamillaris, mamillaris medialis et lateralis). However, the nucleus suprachiasmaticus, where numerous serotoninergic fibers have been reported to occur in the rat, appeared to be almost devoid of these fibers. The infundibular stalk, and the intermediate and posterior lobes of the pituitary contained considerable numbers of immunoreactive fibers. The present study provides a morphological basis for possible clarification of the influence of serotoninergic projections on various neuroendocrine mechanisms in primates. Furthermore, an attempt was made to clarify the differences and similarities concerning the distributional patterns of serotoninergic nerve fibers within the monkey hypothalamus in contrast to the rat hypothalamus.

    Immunohistochemical study on the localization of serotonin fibers and terminals in the spinal cord of the monkey (Macaca fuscata) (1983)

    Notes: Summary A modified procedure of PAP-immunohistochemistry with the use of a rabbit antiserum against serotonin was applied to investigate the pattern of serotonin-containing nerve fibers in the spinal cord of the monkey, Macaca fuscata. The majority of descending serotonin fibers in the white matter is located immediately below the pia mater in the ventrolateral funiculi. Lamina I and the outer zone of lamina II are supplied with numerous serotonin fibers. In the intermediate gray, two prominent bundles composed of longitudinal fibers, i.e., lateral and medial longitudinal serotonin bundles, were recognized at the lateral column and in the vicinity of the central canal, respectively. The motoneurons of the anterior horn are encompassed by fine networks of serotonin fibers and terminals. The results obtained from studies with the monkey spinal cord closely resemble those characteristic of the dog spinal cord as presented in a previous paper, except for portions of the lumbar level. In segments L3–L4, intercalated cell groups between the medial and lateral motor nuclei receive particularly rich inputs of serotonin fibers in the same manner as the neurons of the nucleus intermediolateralis. This peculiar finding may suggest the presence of a specialized nucleus in the anterior column of the simian and also human spinal cord.
