SC213 Lecture Notes - Lecture 14: Optic Chiasm, Commissure, Lateralization Of Brain Function
Document Summary
Refers to the idea that each hemisphere of the brain is specialized for different functions. Each hemispheres is connected to the contralateral (opposite) side of the body. Skin receptors and muscles on the right side of the body are connected to the left hemisphere. Each hemisphere processes visual information from the opposite side of the world. The left and right hemisphere exchange information primarily through a set of axons called the corpus callosum. Information crosses to the other hemisphere with only a brief delay. The two hemispheres are not mirror images of each other. Division of labor between the two hemispheres is known as lateralization. In most humans the left side is specialized for language. The corpus callosum allows each hemisphere of the brain access to information from both sides. Each hemisphere of the brain gets input from the opposite half of the visual world. The visual field is what is visible at any moment.
