INAH 3
INAH 3 (pronounced as I-N-A-H Three), or the third interstitial nucleus of the anterior hypothalamus, is a nucleus found in the anterior hypothalamus. It is one of the four clusters of neurons in the hypothalamus of the human brain, discovered by neuroscientist Simon LeVay.
Etymology
The term INAH 3 is an abbreviation for the third interstitial nucleus of the anterior hypothalamus. The term is derived from the location and order of this particular nucleus in the hypothalamus.
Function
The INAH 3 is believed to play a significant role in sexual orientation, due to its size difference in heterosexual men and homosexual men. However, the exact function of INAH 3 is still a subject of ongoing research.
