The brain has 3 main parts: cerebrum, cerebellum and brain stem.

-Cerebrum

The cerebrum is the largest part of the brain, 85% of the total weight of the brain. The cerebrum has a wrinkled surface, namely the cerebral cortex, which consists of gray matter. Below the cerebral cortex is gray matter. The cerebrum in humans is very large and more important than other parts of the brain. Large parts of the outer brain regulate reading activity, thinking, learning, talking, emotions and planned muscle movements like walking. Cerebrum also controls vision, hearing and other senses. The cerebrum is divided into 2 parts. The left side of the cerebrum controls the right part of the body and the left part of the cerebrum controls the left side of the body. The cerebellar hemisphere is then subdivided into 4 parts:

Frontal lobe: responsible for cognitive function and decision making.

Temporal lobe: responsible for processing memory, combining it with taste, sound, vision, touch and emotional sensations.

Parietal lobe: responsible for processing information about temperature, taste, touch, movement and spatial orientation.

Occipital lobe: responsible for vision.

-Cerebellum

The second largest part of the brain is the cerebellum, which is below the back of the cerebrum. The cerebellum has an important function in motor control and is responsible for coordinating muscle movement and controlling balance The cerebellum consists of gray and white matter and transmits information to the spinal cord and other parts of the brain.

-Brain stem

The brain stem is located at the bottom of the brain, connecting the cerebrum to the spinal cord.
