Villous branches are branches located on the inner surface of the cerebral hemispheres and on the lateral surfaces of the hindbrain hemispheres. They are located near the cerebral ventricles, which are the cavities of the telencephalon and communicate with the large cerebral ventricles. The main function of the villous branches of the brain is participation in the processes of information exchange between brain tissue and lymphatic vessels. Lymphatic fluid moves to the villi of the branches using peristaltic movements of blood vessels. Thus, the villi of the branches perform the task of cleansing the bloodstream of the brain from waste
