The diencephalon is connected above and in front of the cerebral hemispheres; behind the mid-brain. Its upper surface is concealed by the corpus callosum, and is covered by a fold of pia mater, named the tela choroidea of the third ventricle; inferiorly it reaches to the base of the brain.
It comprises:
- thalamencephalon
- thalamus
- corpora geniculata
- epithalamus, consisting of the trigonum habenulae, pineal body and the posterior commissure
- hypothalamus
- posterior part of the third ventricle
