The hypothalamus is a small but crucial part of the brain. It controls functions such as sleep and growth. ... The posterior hypothalamic nucleus and mammillary nucleus are its main nuclei.

One of the main areas GABA is involved in for the sleep-wake cycle is the posterior hypothalamus (PH). The stimulation of the neurons in the PH are known to contribute to wakefulness.

Hypothalamus and pituitary gland Your hypothalamus balances your body by making hormones that it sends to be stored in an area of your pituitary called the posterior pituitary.

The posterior pituitary is located at the base of your brain, attached to the hypothalamus. It’s one of the two lobes that together form your pituitary gland.

Exposure to higher levels of light can help people feel more awake and increase cognitive performance, probably by influencing the activity of parts of a brain region called the hypothalamus, ...

This makes it unlikely that the posterior hypothalamus activity directly mediates the positive impact of light on cognitive performance, and possibly hints at other brain regions being involved ...

These neurons appear to send signals between two parts of the brain -- the back tip, or posterior, of the amygdala and the hypothalamus -- that together regulate emotions including fear, anxiety ...

The authors proposed an intraventricular ‘floating’ electrode inserted in the third ventricle (V3) adjacent to the ventromedian hypothalamus (VMH) in a freely moving Macaca fascicularis to ...

Scans revealed significant activation of the contralateral posterior hypothalamus and ipsilateral dorsal rostral pons as well as activation of the ipsilateral ventrolateral midbrain, which ...

On the other hand, the activity of the posterior hypothalamus was found to be associated with an increased behavioural response to the emotional task. This suggests the association between cognitive ...
