Our brain is divided into 2 halves, or hemispheres, that are connected to each other by the corpus callosum. These two hemispheres control the motion in and receive sensory inputs from the opposite side of our body.

Why is the brain divided into two hemispheres?

In other words, if one part of the brain is taking care of one specific function such as language and speech, then another part remains free to take care of something else, such as facial recognition. ... This may in turn allow the brain to juggle these different functions more efficiently.

Why do they split the brain?

Sperry severed the corpus callosum in cats and monkeys to study the function of each side of the brain. He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain. The split-brain enabled animals to memorize double the information.

What part of the brain controls the eyes?

Occipital lobe.

The occipital lobe is the back part of the brain that is involved with vision.

The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception. The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information.

What does the occipital lobe do?

The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.

Can your brain switch dominance?

In normal people, the switch allows either the left or right hemisphere to be dominant during different mental tasks, with the two sides constantly taking turns. ... He maintains that one hemisphere can be more immature than the other and that this imbalance leads to different mental disorders.
