Definition

Tract which originates from several clusters of cell bodies in the rostral midbrain, the anterior tegmentum and the nucleus of the posterior commissure. The neurons that are part of the nucleus of the posterior commissure have axons which course ventrally toward the anterior tegmentum, while the ventral tegmental clusters of neurons have axons which course dorsally along the posterior commissure and cross the dorsal midline to the contralateral side they then turn posteriorly and extend to the posterior region of the tegmentum and eventually into the hindbrain via the tract of the postoptic commissure. .
