a) Cerebrum, Cerebellum, Brain stem
b) In fact, the brain's oxygen demands are enormous; despite comprising only 2 percent of the body, our brains consume 20 percent of the body's oxygen supply. Scientists have long understood that there is a direct correlation between brain activity and blood flow.

a) Frontal Lobe - Front part of the brain; involved in planning, organizing, problem solving, selective attention, personality and a variety of "higher cognitive functions" including behavior and emotions.
b) Temporal Lobe - There are two temporal lobes, one on each side of the brain located at about the level of the ears. These lobes allow a person to tell one smell from another and one sound from another. They also help in sorting new information and are believed to be responsible for short-term memory.
c) Occipital Lobe - Region in the back of the brain which processes visual information. Not only is the occipital lobe mainly responsible for visual reception, it also contains association areas that help in the visual recognition of shapes and colors. Damage to this lobe can cause visual deficits
d) Parietal Lobe - One of the two parietal lobes of the brain located behind the frontal lobe at the top of the brain.
