Therese, a neuroscientist, is studying the brain of a patient whose corpus callosum has been severed during a treatment for severe epilepsy. She finds that when images or words are displayed in the right half of his eye's visual field, he can describe them. However, when the images are displayed in the left half of his eye's visual field, he cannot describe them. This scenario illustrates
A) integration.
B) lateralization.
C) plasticity.
D) haptic perception.

The scenario illustrates lateralization, which refers to the tendency for some neural functions or cognitive processes to be more dominant in one hemisphere of the brain than the other. In this case, the ability to describe images or words is affected by which hemisphere processes the information, indicating a lateralized brain function. The corpus callosum normally facilitates communication between the two hemispheres, but its severance has led to a situation where the hemispheres cannot share information effectively, highlighting the lateralization of language and descriptive abilities to the left hemisphere (which processes information from the right visual field).
