Name: tract of the commissure of the caudal tuberculum
Synonyms: TCPT, tract of the commissure of the posterior tuberculum
Definition: Tract that extends from the intersection of the tract of the postoptic commissure and supraoptic tract that projects caudally across the hypothalamus and into the commissure of the caudal tuberculum. The axons appear to originate from a symmetric group of neurons in the forebrain that travel caudally into the diencephalon and then decussate, with some axons continuing to travel longitudinally and join other axons crossing the midline. There does not appear to be a clear ortholog of the TCPT in mammals; and the function(s) of the TCPT are not currently known.
