Term
what is the location, function, and associated deficit upon lesion of the lateral preoptic nucleus?
Definition
It is in the preoptic level, promotes NREM sleep and if lesioned produces insomnia
Term
what is the location, function, and associated deficit upon lesion of the medial preoptic nuclei?
Definition
it is located at the preoptic level performs thermoregulation, neuroendocrine and reproductive behavior. If lesioned --> hyperthermia
Term
what is the location, function, and associated deficit upon lesion of the anterior nucleus?
Definition
at the suproptic level. upregulates parasympathetics and decrease thermogenesis. If lesioned causes hyperthermia.
Term
what is the location, function, and associated deficit upon lesion of the suprachiasmatic nucleus?
Definition
located in the supraoptic level and controls circadian rhythm. If lesioned causes disruption of the dirunal cycle.
Term
what is the location, function, and associated deficit upon lesion of the paraventricular nucleus
Definition
located in the supraoptic level and is neuroendocrine in nature.
Term
what is the location, function, and associated deficit upon lesion of the supraoptic nucleus?
Definition
located in the supraoptic level and is neuroendocrine in function.
Term
what is the location, function, and associated deficit upon lesion of the posterior nucleus?
Definition
located in the mammillary level and increases sympathetics and thermogenesis. If lesioned can produce horner's syndrome and poikilothermia.
Term
what is the location, function, and associated deficit upon lesion of the tuberomammillary nucleus?
Definition
located in the mammillary level and controls wakefullness. If lesioned causes hypersomnia.
Term
what is the location, function, and associated deficit upon lesion of the mammillary body?
Definition
located in the mammillary level it controls the memory consolidation and if lesioned causes anterograde amnesia.
Term
what is the location, function, and associated deficit upon lesion of the lateral hypothalamus?
Definition
located in the mammillary and lateral zone and is responsible for feeding and wakefulness. If lesioned, causes anorexia and narcolepsy.
Term
what is the location, function, and associated deficit upon lesion of the ventromedial nucleus?
Definition
located at the tuberal level and is responsible for feeding and satiety. If lesioned causes hyperphagia and obesity.
Dorsomedial does same thing.
Term
what is the location, function, and associated deficit upon lesion of the arcuate nucleus?
Definition
located at the tuberal level it is associated with feeding and neuroendocrine functions. If lesioned causes feeding dysfunctions.
Term
what is the location, function, and associated deficit upon lesion of the periventricular nucleus?
Definition
in the periventricular zone and functions as neuroendocrine.
