refers to the largest of three divisions of the rostral third of the periaqueductal gray as segmented in the functionally defined motor periaqueductal gray. It is a wide band of cells bounded by the other divisions: medially by the medial division of the periaqueductal gray and laterally, through a portion of its extent, by the rostrolateral division of the periaqueductal gray. Functionally the motor periaqueductal gray belongs to the behavior control column of the cerebrospinal trunk ( Swanson-2004 ).
