What is the function of the thalamic adhesion?

The thalamic adhesion, also known as the massa intermedia, serves the specific function of connecting the two thalami, which are key structures located centrally in the brain. This connection allows for communication between the left and right hemispheres of the thalamus, which is involved in processing and transmitting sensory information to the cerebral cortex. By linking the two thalami, the thalamic adhesion may help in coordinating sensory input and contributes to the integration of sensory information before it reaches higher brain areas.

Understanding this connection is crucial, as the thalamus itself plays a pivotal role in sensory perception, motor function, and the regulation of consciousness and alertness. Other functions attributed to the thalamus, such as emotion regulation or motor coordination, do not directly involve the thalamic adhesion. Instead, those functions are more broadly associated with other areas within the thalamus or different brain regions altogether.
