The orexins (or hypocretins) are neuropeptide transmitters made exclusively in hypothalamic neurons that have extensive CNS projections. Previous studies reported that this system is most strongly associated with feeding, arousal and the maintenance of waking. We review here recent studies that reveal a novel and important role for the orexin/hypocretin neuronal system in reward processing and ...
The memory mechanisms of conditioned taste aversion (CTA) were examined using electrophysiological methods. Presentation of the aversive taste to CTA trained animals inhibited unit activity in gustatory cortex, amygdala and ventromedial hypothalamus and caused delayed excitation of neurons in lateral hypothalamus. Lick-triggered rewarding stimulation of medial forebrain bundle substituted the t...
We report a morphological and biochemical analysis on the presence, distribution and quantification of vasotocin in the hypothalamus and limbic region of the budgerigar Melopsittacus undulatus, using immunohistochemistry on serial sections and competitive enzyme linked immunoadsorbent assay measurements on tissue extracts. Analysis of the sections showed large vasotocin-immunoreactive neurons i...
Objective: Appetite is affected by the metabolic profile, infections and nutritional shape in domestic animals. Regulation of appetite involves many complex physiological processes. Ghrelin well known appetite-enhancing hormone. The also managed lateral hypothalamus. On other hand, ventromedial nucleus most commonly associated with satiety. Brotizolam, member 1,4-benzodiazepines derivative, blo...
The acute self-stimulation of the medial forebrain bundle was reported to induce the expression of c-Fos, the protein product of c-fos, an immediate early gene, in the central nervous system. In the present study, we examined regional changes in c-Fos expression in several reward-related areas of rat brain in response to short- and long-term exposure to self-stimulation of the medial forebrain ...
Afferent fibers from the amygdala to subdivisions of lateral, ventromedial and dorsomedial hypothalamic nuclei were investigated in rat by retrograde transport of horseradish peroxidase. Small (intranuclear size) peroxidase deposits were placed in hypothalamic nuclei by iontophoresis of a tracer solution containing poly-L-alpha-ornithine which greatly limited diffusion. The medial, central and ...
