The brain is divided into two hemispheres: the left hemisphere and right hemisphere. Each of the hemispheres have all four lobes of the cerebrum (frontal lobe, temporal lobe, parietal lobe and occipital lobe), but they have different functions.
For example, language tends to be a left hemisphere function. The ]]>University of Washington]]> states that 95 percent of right-handed people and 60 to 70 percent of left-handed people have language on their left hemisphere. Other left hemisphere functions are math, logic and controlling the right side of the body, while other right hemisphere functions are music, spatial abilities, face recognition, visual imagery and controlling the left side of the body.
The two hemispheres are connected with the corpus callosum, which is made up of 200 to 250 million nerve fibers.
What happens if the corpus callosum is cut?
