Diencephalon. Located between the cerebral hemispheres and above midbrain. Composed largely of gray matter. Surrounds 3. rd. ventricle. Includes:. Thalamus. Hypothalamus. Optic tracts. Optic . Diencephalon. This represents the central core of the forebrain and is surrounded by the cerebral hemispheres. It is made up of three major paired structures: . The thalamus. The hypothalamus. The epithalamus. Divisions of diencephalon:. Diencephalon. Thalamus:. It is an important relay station has an egg shaped and it represents a large mass of gray matter. The two thalami are situated on each side of the midline slit like cavity (the third ventricle). Lateral to each thalamus is the internal capsule (white matter).. 1 Corresponding AuthorResearch Fellow, Tata Medical Centre, India;karthikeyanr@gmail.com Rupani K.
