Thalamus.
The diencephalon consists of thalamus, hypothalamus, and epithalamus.
The thalamus is situated at the top of the brain stem, connecting the brain to the spinal cord and vertebrates. The thalamus wraps around the third ventricle, making up the upper part of the ventricle wall.
The two parts are the thalamus and the hypothalamus. The hypothalamus is beneath the thalamus, so the answer to your question is the hypothalamus.
