Question

Quizplus · Accepted Answer

The corpus callosum is responsible for connecting the left and right hemispheres of the brain, and damage to the body of the corpus callosum can impair the communication between them. Matching left and right limb position with eyes closed requires cooperation between the two hemispheres, so damage to the corpus callosum could impair this ability. The other options listed involve more localized functions that are less likely to be affected by damage to the body of the corpus callosum.
