The brain can be divided into four lobes - the frontal, parietal, occipital, and temporal lobes. Each lobe is associated with different functions. The frontal lobe is involved in reasoning, motor skills, and language. The parietal lobe processes sensory information like touch. The temporal lobe includes the auditory cortex and hippocampus. The occipital lobe contains the visual cortex and interprets visual stimuli.
