The cerebrum (right and left) is the upper, front portion of the brain and consists of two hemispheres, or halves. The two hemispheres are connected by the corpus callosum, which is a large bundle of nerve fibers. The cerebrum can be divided into four lobes: frontal lobe, parietal lobe, occipital lobe, and temporal lobe. The cerebrum is the largest portion of the brain. It oversees many everyday activities. These include motor function, cognitive abilities (thinking and reasoning), sensory impulse interpretation, speech and language, bowel and bladder control, sexual desire, and emotional control.
