Splenium

Splenium is the posterior part of the corpus callosum, the largest white matter structure in the brain. It is responsible for transmitting information between the two hemispheres of the brain.

Anatomy

The splenium is located at the back of the corpus callosum, just above the cerebellum. It is shaped like a crescent and is the thickest part of the corpus callosum. The splenium connects the two cerebral hemispheres and allows them to communicate with each other.

Function

The primary function of the splenium is to facilitate communication between the two hemispheres of the brain. It does this by transmitting information from one hemisphere to the other. This information can be sensory, motor, or cognitive in nature. The splenium is particularly important for visual processing and spatial awareness.

Clinical significance

Damage to the splenium can result in a variety of neurological disorders. These can include alexia (a disorder affecting the ability to read), agraphia (a disorder affecting the ability to write), and apraxia (a disorder affecting the ability to carry out purposeful movements). In addition, damage to the splenium can result in split-brain syndrome, a condition in which the two hemispheres of the brain are unable to communicate effectively.
