Meynert's commissure

Last revised by Daniel J Bell on 3 May 2022

Meynert’s commissure, also known as dorsal supraoptic commissure, is one of three white matter tracts that comprise the supraoptic commissure 1,2. The remaining two tracts that comprise the supraoptic commissure are Gudden’s commissure (ventral supraoptic decussation) and the anterior hypothalamic commissure of Gasner 1.

Gross anatomy

The fibers that comprise Meynert’s commissure are located immediately posterior to the optic chiasm 1. Fibers within the commissure are proposed to interconnect components of the basal ganglia (subthalamic nuclei and globus pallidus) with the lateral geniculate bodies and superior colliculi 1,2.

History and etymology

Meynert’s commissure is named after Theodor Hermann Meynert (1833-1892), a German-Austrian anatomist and pathologist 3,4.
