Q. Explain Thalamus and Hypothalamus ?

Thalamus and Hypothalamus: The thalamus is situated in the forebrain at the uppermost part of the diencephalon (posterior part of the forebrain). It's an important part of the brain as all the sensory information we gather enters into this part, which is then sent via neurons into the cortex. All sensory inputs to the brain, except that of the sense of smell, are through the thalamus. The hypothalamus lies ventral to the thalamus and is a part of the diencephalon. It deals with the function of homeostasis (metabolic equilibrium), thirst, hunger, emotions, control of autonomic nervous system and the pituitary gland. The hypothalamus is involved with the body's vital drives and activities, such as eating, drinking, temperature regulation, sleep, emotional behaviour, and sexual activity. It controls the functions of many internal body organs and helps coordinate activities of the brain stem.
