The corpus callosum is responsible for A) verbal processing. B) relaying information between the right and left hemispheres. C) speech production. D) sleep.
The corpus callosum is a collection of axons in the central part of the brain which connects the two hemispheres - so the correct answer is B): relaying information between the right and left hemispheres. In patients with severe epilepsy this tissue can be cut through and they live then a life with two independent hemispheres - but surprisingly many of them can function without any problems.
