What does the lateral preoptic area do
Involved in non-rem sleep onset
1 of 19
Other functions of the preoptic area
thermoregulation, thirst, sexual behavior
2 of 19
Paraventricular Nuclei
water balance and stress
3 of 19
supraoptic nuclei
water balance
4 of 19
suprachiasmatic nuclei
biological clock, circadian rhythms
5 of 19
Ventromedial Nuclei
satiety centre, destruction results in overeating
6 of 19
Arcuate nuclei
inhibits prolactin release by dopaergic neurons, produces hypothalamic releasing factors
7 of 19
Homeostatic functions of the hypothalamus
Hormones, plasma osmolality, body temperature, body weight, nutrients
8 of 19
circadian regulatory functions
approx 24 sleep wake cycle, seasonal breeding, hormonal regulation
9 of 19
Allostatic challenges
fight or flight, mating, birth, suckling
10 of 19
Where does exteroceptive information to the hypothalamus come from?
Visual - retina. Olfactory system.
11 of 19
Where does interoceptive information to the hypothalamus come from?
viscera, body temperature, steroid hormones, osmolarity, glucose level, cytokines
12 of 19
Where lacks the blood brain barrier?
The circumventricular organs - the median eminence, the posterior pituitary, the pineal gland and the OVLT
13 of 19
Example of something that can enter through the circumventricular organs
cytokines - such as interleukin 1beta
14 of 19
Three types of output from the hypothalamus
Neuroendocrine, autonomic, behavioural
15 of 19
Where is vasopressin formed, what is it's function
Singalled by the supraoptic nuclei. Antidiuretic.
16 of 19
What happens if you get a lesion in the lateral hypothalamic area?
loss of appetite, starvation
17 of 19
What happens if you lesion the ventromedial nucleus
RAGE - emotional behavior
18 of 19
Melatonin is sent from which gland to the suprachiasmatic nucleus
the pineal
19 of 19
