Thalamus, epithalamus, hypothalamus....
diencephalon
There are two structures that make up the Diencephalon. The main structure of the diencephalon is hypothalamus thalamus and the second is the subthalamus.
Its the Hypothalamus
Diencephalon
The Hypothalamus.
Pineal Gland
i think it is thalamus
The thalamus is part of the limbic system (or more specifically, it is the largest structure in the diencephalon).
The two optic nerves reach the diencephalon at the optic chiasm, a structure located at the base of the brain where the nerves partially cross over each other. From the optic chiasm, the optic nerves continue on to the thalamus within the diencephalon.
The pineal gland is a cone-shaped structure attached to the upper posterior portion of the diencephalon. It secretes melatonin, a hormone that regulates sleep-wake cycles and circadian rhythms in the body.
Diencephalon
The two major components of the diencephalon are the thalamus and the hypothalamus.
