The human brain is the most important organ in the body. It is the nervous system's control centre, controlling all voluntary and involuntary movement and action. All cognitive functions, such as memory, language, and thought, are also controlled by the brain. The cerebrum, cerebellum, and brainstem are the three main parts of the brain.

The cerebrum is the largest part of the brain and is responsible for most higher cognitive functions, such as decision-making, planning, and problem-solving. 

The cerebellum is in charge of the coordination of movement and balance.

The brainstem controls basic functions such as breathing, heart rate, and blood pressure. 

The brain is divided into two halves: left and right. The left hemisphere is in charge of language and logical thought, while the right hemisphere is in charge of creativity and intuition. Even when we are sleeping, the brain is constantly active. It regulates all of our bodily functions and processes sensory information.


The average adult's brain weighs about 3 pounds and is 60% fat. Water, protein, carbohydrates, and salts make up the remaining 40%. The brain is not a muscle in and of itself. It is made up of blood vessels and nerves, as well as neurons and glial cells.

Functions of Brain

What is the definition of the brain according to you

  • One of the most important functions of the brain is to control our thoughts and emotions. The brain is responsible for sending signals to our body that tell us how to feel and react in different situations.
  • The brain is also responsible for controlling our movement. When we want to move our body, the brain sends signals to our muscles telling them what to do.
  • The brain is also responsible for storing memories. When we experience something, the brain stores that information so that we can remember it later.
  • Control of voluntary and involuntary movement
  • Processing of sensory information
  • Generation of thoughts and emotions
  • Storage of memories
  • Control of the autonomic nervous system

As you can see, the brain is a very complex organ that is constantly working to keep us alive and functioning properly.
