What is posterior commissure?

The posterior commissure is a small white matter tract located in the brain that connects the two hemispheres of the brain. It is situated in the caudal part of the diencephalon, specifically in the area known as the tectum.

The main function of the posterior commissure is to facilitate communication between the left and right hemispheres of the brain. This allows for coordination and integration of sensory and motor information between the two sides of the brain.

Damage to the posterior commissure can result in various neurological symptoms, including sensory and motor deficits, as well as problems with coordination and balance.

Overall, the posterior commissure plays a vital role in the integration of information and the coordination of brain functions, making it an important structure in the brain.
