supraoptic nucleus
Acronym: SO
The term supraoptic nucleus refers to a group of cells at the ventral and lateral extremes of the hypothalamus as demonstrated by Nissl stain in the human ( Mai-1997 ), the macaque ( Paxinos-2009 ), the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ). Located close to the optic chiasm and optic tract, it is composed of two parts, the dorsolateral part of the supraoptic nucleus and the retrochiasmatic part of the supraoptic nucleus. Some authors regard the retrochiasmatic area, which is relatively small in the human, to be a 'tuberal part' of the supraoptic nucleus, not a distinct entity ( Mai-1997 ).

Also known as: supraoptic nucleus of hypothalamus, Nucleus supraopticus, Nucleus supraopticus hypothalami
