What is interthalamic adhesion?

Interthalamic adhesion, also known as the massa intermedia, is a small bridge of grey matter that connects the two thalamic bodies in the brain. This structure is present in around 70-80% of individuals, with variations in size and shape.

The interthalamic adhesion plays a role in facilitating communication and coordination between the two thalamic bodies, which are important relay stations for sensory and motor information in the brain. It is also thought to be involved in regulating sleep cycles, memory, and certain emotional responses.

While the function of the interthalamic adhesion is not fully understood, abnormalities in its size or shape have been associated with certain neurological disorders, such as schizophrenia and autism. Research continues to investigate the role of this structure in brain function and its potential implications for various cognitive and behavioral processes.
