precommissural nucleus
Acronym: PrC
The term precommissural nucleus refers to a group of cells located rostral and ventral to the posterior commissure at the rostral extreme of the midbrain tegmentum. It is so named because of it's location rostral to the commissural nucleus of the periaqueductal gray ( Swanson-2004 ). It is found in the human ( Paxinos-2012 ), macaque ( Paxinos-2009a ), rat ( Swanson-1998 ), and mouse ( Paxinos-2001 ).
     The precommisural nucleus is one of eleven groups of cells comprising the motor periaqueductal gray ( Swanson-2004 ). Functionally the motor periaqueductal gray belongs to the central gray of the behavior control column ( Swanson-2004 ).
