Lobes of the Brain by Dr. Sagun Tuli

The largest part of the brain, the cerebrum has a wide range of responsibilities that contribute to perception of stimuli, personality, and memory. Within the cerebrum, doctors have identified four lobes, which each control a portion of our actions. Occipital Lobe: This section of the brain is located at the back of the head and specializes in visual processing. It does this through a structure called the visual cortex, which coats the surface of the lobe.Temporal Lobe: This lobe specializes in interpretation of auditory stimuli. Located at the bottom in front of the occipital lobe, the temporal lobe is also closely linked to both speech and memory.Parietal Lobe: Located in front of the occipital lobe and on top of the temporal lobe, the parietal lobe is associated with orientation, movement, and motor skills.Frontal Lobe: Just behind the forehead rests the frontal lobe, which is responsible for both intelligence and personality.About the author: Dr. Sagun Tuli is a neurosurgeon with over a decade of experience.
