What condition results from cutting the corpus callosum?

When the corpus callosum is severed, the condition that results is referred to as "split brain." The corpus callosum is the major structure that connects the left and right hemispheres of the brain, allowing for interhemispheric communication. By cutting this structure, the two sides of the brain can no longer effectively communicate with each other. This can lead to a range of cognitive and behavioral effects that are characteristic of split-brain syndrome, such as difficulties in coordination between hemispheres, and isolated processing of stimuli in either hemisphere.

In split-brain patients, specific functions may become lateralized. For example, a patient may be able to verbally identify objects presented to the right visual field (processed by the left hemisphere) but might not be able to name objects shown to the left visual field (processed by the right hemisphere), even though they can often draw or point to them. This showcases the division of processing capabilities that occurs when the corpus callosum is cut, highlighting how the brain is organized and the roles that each hemisphere plays in perception and cognition.

Other options, such as neurogenesis, brain plasticity, and neuron degeneration, pertain to different processes in brain functioning and development, but they do not specifically describe
