The human brain is the largest and most important part of the central nervous system, which controls the neuromuscular and endocrine systems of the entire body and also receives sensory input from the various organs of the body. It is made up on the brain stem and lower brain, the midbrain, and the neocortex.

The brainstem and lower brain control fight, flight, feeding, and reproductive drives necessary for survival, and also control our level of alertness. The brainstem also controls the autonomic nervous system, responsible for heart rate and breathing.

The midbrain controls our emotions, various reflexes, and also interconnects the lower brain to the neocortex. It is extremely important in encoding memories and determining emotional "weight" assigned to various neural processes (thoughts, sensations, memories, etc.).

The neocortex is the outermost brain, and is where most of the "intelligent" processing takes place. It is subdivided into four lobes: frontal lobe (responsible for consciousness, rational thought, and motor control of the body); parietal lobe (responsible for processing sensory input from the body); temporal lobe (responsible for hearing and long-term memory encoding); and the occipital lobe (responsible for the five levels of visual processing for sight).
