The human brain is a complex organ that allows us to think, move, feel, see, hear, taste, and smell. It controls our body, receives information, analyzes information, and stores information. It is made up of nervous tissue. The brain produces electrical signals, which, together with chemical reactions, helps various parts of the body communicate with each other. Due to electrical impulses, messages can be transmitted very quickly across the body.

Different parts of the brain carry out different functions. In general, the following functions are carried out by brain:

i) Brain is the central control unit of the body. It receives information, analyses this information and sends out messages that control body functions.

ii) Brain stores information in the form of memory.

iii) It controls voluntary movements, balance of the body, thermoregulation, circadian rhythms, hunger and thirst and human behaviour.

iv) It also controls the functioning of vital involuntary organs and several endocrine glands.

v) Also, processing of vision, hearing, intelligence, emotions and thoughts is also a function of brain.
