Quizplus · Accepted Answer

The corpus callosum connects the left and right hemispheres of the brain, facilitating interhemispheric communication. When visual stimuli are presented to the left visual field, they are processed by the right hemisphere, and vice versa. Language functions are primarily located in the left hemisphere. After severing the corpus callosum, stimuli presented to the left visual field (processed by the right hemisphere) cannot be easily verbalized because the information cannot be transferred to the language centers in the left hemisphere. However, stimuli presented to the right visual field can be named because they are directly processed by the left hemisphere, where language functions reside.
