What is the main function of the corpus callosum?

The main function of the corpus callosum is to link the two cerebral hemispheres. This large bundle of neural fibers acts as a communication bridge between the left and right sides of the brain, facilitating the transfer of information and coordination of activities between the two hemispheres. It allows for the integration of sensory and cognitive processes, enabling a unified response to stimuli and supporting overall brain function.

While processing visual information is a critical function of certain brain regions, it's primarily handled by areas within the occipital lobe, rather than the corpus callosum itself. Memory storage involves various brain regions, including the hippocampus and the cerebral cortex, and is not a function associated with the corpus callosum. The regulation of breathing is primarily controlled by the brainstem and does not relate to the role of the corpus callosum in interhemispheric communication.
