What are the function of fore-brain? Explain its structure.

Fore brain is the largest and most well-developed part of the brain. The main parts of fore brain are the cerebrum, thalamus and hypothalamus. Cerebrum is the main thinking part of the brain and it performs functions of thinking, consciousness, knowledge etc. The cerebral hemispheres consist of grey matter which is called the cortex. Both the cerebral hemispheres are connected by corpus callosum. Thalamus diagnoses the sensory information transmitted to the brain. Hypothalamus (found in the diencephalon part) links the nervous system to endocrine system via the pituitary gland, controls metabolism, regulates the body temperature, regulates water balance, sleep etc. It is the center for hunger, thirst, sleep, temperature, fatigue etc.
