|
Lateral preoptic nucleus
|
In lateral zone
Role in NREM sleep via inhibition of lateral tuberal nucleus |
|
|
Lateral hypothalamic area
|
In lateral zone
Eating when stimulated, anorexia/starvation when inhibited |
|
|
Lateral tuberal nucleus
|
In lateral zones
Contains nn. that release histamine throughout brain, role in arousal, attention |
|
|
Medial preoptic nucleus
|
In preoptic area of medial zone
Nn. regulate gonadotropin secretion from anterior pituitary, contain sexually dimorphic interstitial nucleus of anterior hypothalamus |
|
|
Suprachiasmatic nuclei
|
In supraoptic area of medial zone
Receives input from retina, optic chiasm, role in circadian rhythms, vision |
|
|
Anterior hypothalmic nucleus
|
In supraoptic area in medial zone
Involved in hot temp regulation, triggers heat loss, lesion causes hyperthermia |
|
|
Paraventricular nucleus
|
In supraoptic area of medial zone
Nn. synthesize posterior pituitary hormones, i.e. CRH, oxytocin and vasopressin, also projects to preganglionic sympathetic nn. in SC |
|
|
Supraoptic nuclei
|
In supraoptic area of medial zone
Nn. synthesize vasopressin and oxytocin, project via supraopticohypohysesal tract to post pituitary |
|
|
Dorsomedial nucleus
|
In tuberal area of medial zone
Stimulation causes aggression, also role in BP control |
|
|
Ventromedial nucleus
|
In tuberal area of medial zone
Inhibits urges to eat, may function in satiety center, lesion causes hyperphagia, aggressive behavior |
|
|
Arcuate nucleus
|
In tuberal area of medial zone
Controls release of anterior pituitary hormones by synthesizing hypothalamic releasing/inhibiting factors |
|
|
Posterior nucleus
|
In mammillary area of medial zone
Role in cold temperature regulation, lesions cause poikilothermia |
|
|
Mammillary nucleus
|
In mammillary area of medial zone
In mammillary bodies, receives input from hippocampus via fornix, projects to anterior nucleus of thalamus via mammillothalamic tract |
