AP PSYCHOLOGY

Detailed explanation-1: -There is evidence of specialization of function-referred to as lateralization-in each hemisphere, mainly regarding differences in language functions. The left hemisphere controls the right half of the body, and the right hemisphere controls the left half of the body.

Detailed explanation-2: -The hemispheres communicate with each other through the corpus callosum which is a bundle of fibers between the hemispheres. Each hemisphere controls muscles and glands on the opposite side of the body (i.e. the right side of the brain or hemisphere controls the left side of the body.)

Detailed explanation-3: -The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body. Anatomy of the brain, showing the cerebrum, cerebellum, brain stem, and other parts of the brain.

Detailed explanation-4: -The contralateral organization of the forebrain (Latin: contra‚ against; latus‚ side; lateral‚ sided) is the property that the hemispheres of the cerebrum and the thalamus represent mainly the contralateral side of the body.

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).
