Dencephalon is the part of the forebrain and includes three parts- epithalamus,thalamus and the hypothalamus.
Epithalamus is a non-nervous part , it remains fused with pia mater and forms the anterior choroid plexus.
The thalamus is located between the midbrain and the cerebral cortex. It filters sensory information and directs them to appropriate parts of cerebrum.
Hypothalamus is located beneath the thalamus. It is an integrating center for many important homeostatic functions.
