    Notes: Summary D-C potential changes were evoked in the sensorimotor cortex and the hypothalamus of unanesthetized cats with chronically implanted electrodes by repetitive stimulation of the mesencephalic reticular formation. Stimulation at 30 to 300 p/sec. frequencies induced negative d-c shifts which were quite abrupt in onset, starting after the second or third shock with a peak of negativity reached within the first 50 to 100 msec of the 1 second duration of stimulation. Typically these negative shifts were sustained for the duration of stimulation with a prolonged 1 to 1.5 second return to baseline after termination of stimulation. Such d-c shifts were relatively independent of the site of the reference electrode but highly dependent on the location of the “active” recording electrodes and the stimulating electrodes. Reasons have been advanced to suggest that these negative d-c shifts reflect summated neuronal discharge in the immediate environs of “active” recording electrodes in the cerebral cortex and hypothalamus. In contrast to the consistent, stimulus-locked negative d-c shifts, less consistent changes, usually positive in polarity, were observed to begin 2 to 3 seconds after termination of RF stimulation. These slower d-c changes were highly dependent on the site of the reference electrode and the physical state of tissue at the electrode tip and therefore far less directly related to neuronal events in cortical and hypothalamic tissue.

    Notes: Summary Our immunocytochemical investigation of the magnocellular neuroendocrine system in the goldfish hypothalamus reveals enkephalin (ENK)-containing neurons interspersed among the vasotocin (VT)- and isotocin (IT)-containing neurons of the preoptic nucleus. The perikarya of the ENK, VT, and IT neurons do not show distinct morphological differences at the level of light microscopy and are not located preferentially within the nucleus. Separate ENK, VT and IT fibers course laterally and ventrally through the hypothalamus as they descend toward the pituitary gland. All three fiber types form terminals around blood vessels in the neurohypophysis.

    Notes: Summary Isotocinergic (IT) neurons show physiological and morphological characteristics that are similar to those of other preoptic neuroendocrine cells in the goldfish. Preoptic IT cells show resting membrane potentials of 20–55 mV, action potentials of up to 100mV, and physiological evidence of axonal branching. Dye-marked IT cells measure 14–56 μm, their dendrites projecting to the ependyma and into the hypothalamic neuropil, their multiple beaded axons projecting to the pituitary. Indirect immunofluorescence identifies these dyemarked cells as IT. By combining electrophysiological, dye-marking and immunocytochemical techniques we can now, for the first time, study single, antidromically-identified peptidergic neurons of a specific type in vertebrate and invertebrate species.

    Notes: Summary Our immunocytochemical investigation of the magnocellular neuroendocrine cells in the cat hypothalamus reveals a mixture of vasopressin (VP)- and oxytocin (OT)-containing neurons in the supraoptic (NSO), the paraventricular (NPV) and in five accessory nuclei (NAC). We describe the lateral hypothalamic nucleus (NLH), a new accessory nucleus, lying at the junction of the internal capsule and pallidum, and possibly involved in drinking behavior. Previously characterized incompletely in mammals, the four other accessory nuclei consist of the circularis (NC), anterior fornical (NAF), posterior fornical (NPF) and retrochiasmatic (NRC). The two peptidergic cell types, VP and OT, are equally mixed in the NPV and the NAC, but in the NSO VP neurons predominate. The perikarya of these VP and OT neurons do not show distinct morphological differences at the level of light microscopy. The organization of magnocellular neurosecretory neurons in the cat hypothalamus closely resembles that described in other mammals with the exception of the unique presence of the lateral hypothalamic accessory nucleus.
