Pretectum

Pretectum (pronunciation: preh-tek-tuhm) is a region of the brain that is involved in various functions, including the control of pupil size and certain aspects of eye movement.

Etymology

The term "pretectum" is derived from the Latin words "pre", meaning "before", and "tectum", meaning "roof". This is in reference to its location in the brain, which is anterior to the tectum.

Function

The pretectum is primarily involved in the control of pupil size and certain aspects of eye movement. It receives input from the retina and sends output to the Edinger-Westphal nucleus, which controls the pupil constriction in response to light. It also plays a role in the regulation of circadian rhythms and sleep.
