AP PSYCHOLOGY

Detailed explanation-1: -Each hemisphere is in charge of the opposite side of the body, so your right brain controls your left hand. The right hemisphere also takes in sensory input from your left side and vice versa. The brain is segmented into regions called lobes. Your lobes isolate your brain’s functions to specific areas.

Detailed explanation-2: -The brain is divided into two parts called hemispheres, the right and the left. The right hemisphere of your brain controls the left side of your body. The left hemisphere of your brain controls the right side of your body. Some functions are controlled by both.

Detailed explanation-3: -The two sides of the brain are joined at the bottom by the corpus callosum. The corpus callosum connects the two halves of the brain and delivers messages from one half of the brain to the other. The surface of the cerebrum contains billions of neurons and glia that together form the cerebral cortex.

Detailed explanation-4: -The left brain handles reading, writing, and calculations. Some call it the logical side of the brain. The right brain is more visual and deals in images more than words.

Detailed explanation-5: -The two hemispheres of the brain control two different parts of the body because the nerves that travel down from the brain to the periphery (hands for example) cross over at the medulla (pyramid decussations to be specific).
