The dorsomedial hypothalamic nucleus in autonomic and neuroendocrine homeostasis.
Median eminence and ventromedial hypothalamus have in the past been the principal foci of research in neuroendocrine and neurovisceral control mechanisms. The present report provides an overview of work involving the dorsomedial hypothalamic nucleus (DMV). This structure is located dorsal to the ventromedial hypothalamic nucleus (VMN) to the plane of the dorsal premammillary nucleus. Fibers fro...
متن کاملModel of voluntary ethanol intake in zebrafish: Effect on behavior and hypothalamic orexigenic peptides
Recent studies in zebrafish have shown that exposure to ethanol in tank water affects various behaviors, including locomotion, anxiety and aggression, and produces changes in brain neurotransmitters, such as serotonin and dopamine. Building on these investigations, the present study had two goals: first, to develop a method for inducing voluntary ethanol intake in individual zebrafish, which ca...
متن کاملRole of hypothalamic neuropeptide Y and orexigenic peptides in anorexia associated with experimental colitis in the rat.
Neuropeptide Y (NPY) is thought to play a crucial role in the normal hypothalamic response to starvation. After a period of food restriction, increased release of NPY induces hunger and hyperphagia, and helps to restore body weight to its set point. Persistent anorexia in rats with experimental colitis implies failure of this adaptive feeding response. In vivo NPY release and regional hypothala...
متن کاملThe Orexigenic Peptides in Children with Celiac Disease
Celiac disease is defined as a permanent gluten intolerance, which if untreated leads to malnutrition. The effect of that disease on the gut-brain axis remains unknown. This paper reports the level of plasma ghrelin, orexin A and B in a group of fifteen 8.6 ± 3.4-year-old children with untreated celiac disease and experimentally maintained on a gluten-free diet. A group of 15 age-matched health...
متن کاملExercise training differentially affects intrinsic excitability of autonomic and neuroendocrine neurons in the hypothalamic paraventricular nucleus.
Oxytocinergic and vasopressinergic brain stem projections have been shown to play an important role in mediating cardiovascular adjustments during exercise training (ET). The aim of the present work was to determine whether the intrinsic excitability of hypothalamic neurons giving rise to brain stem peptidergic projections is altered as a consequence of ET. Whole cell patch-clamp recordings wer...
