Anatomical terms of neuroanatomy |
INAH-3 is the short form for the third interstitial nucleus of the anterior hypothalamus, and is the sexually dimorphic nucleus of humans. INAH-3 is significantly larger in males than in females regardless of age.[1] One study has shown that INAH-3 is larger in heterosexual males than in homosexual males and heterosexual females, although this data has not been successfully reproduced.[2]
