Ventral supraoptic decussation

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

Gross anatomy

The fibers that comprise Gudden’s commissure are located immediately posterior to the optic chiasm ¹. There is some conjecture regarding the path of fibers within the commissure - Jinkins ¹ and Gray et al ³ suggest that the fibers with Gudden’s commissure connect the medial geniculate bodies ¹, whilst Clarke et al ² propose it contains fibers arising from the reticular formation with the pons that then ascend with the medial longitudinal fasciculus ².

History and etymology

Gudden’s commissure is named after Johann Bernhard Aloys von Gudden, a German neuroanatomist and psychiatrist ⁴. Gudden was credited with discovering the commissure in 1870 ⁵.
