Anterior commissure
Anterior Commissure
The Anterior Commissure (pronounced: an-TEER-ee-or kuh-MISH-er) is a bundle of nerve fibers connecting the two cerebral hemispheres of the brain. It is smaller and evolutionarily older than the corpus callosum, which is another structure serving a similar purpose.
Etymology
The term "Anterior Commissure" is derived from Latin, with "anterior" meaning "before" or "in front of", and "commissure" referring to a place where two things are joined. In this context, it refers to the joining of the two hemispheres of the brain.
Function
The Anterior Commissure plays a crucial role in the bilateral communication between the two hemispheres of the brain. It is involved in several functions, including olfaction (sense of smell) and sexual behavior. It also plays a role in the transfer of visual information from one hemisphere to the other.
