The cerebrum includes two hemispheres, and each consists of four lobes: frontal, parietal, temporal, and occipital lobes.
The frontal lobe is involved in planning, reasoning, problem solving, and movement (primary motor area within the precentral gyrus) as well as in the motor component of speech (Broca area).
The parietal lobe is important in sensation (primary somatosensory area within the postcentral postcentral gyrus), orientation, recognition, and visuospatial skills. It is also involved in carrying out complex movements.
The temporal lobe is important in perceiving auditory stimuli, understanding speech (Wernicke area) and memory (hippocampus).
The occipital lobe is important in visual processing and contains the primary visual cortex.
