The human brain is divided into three major areas: forebrain, midbrain, and hindbrain.
The forebrain consists of the cerebral cortex, the thalamus, and the hypothalamus. The cerebral cortex is the largest part of the brain and is divided into 4 major lobes. The frontal lobe controls reasoning, movement, emotions, and problem solving. The parietal lobe controls movement, orientation, recognition, and perception. The occipital lobe controls vision. The temporal lobe controls memory, speech, and auditory functions. The thalamus controls sensory functions and movement while the hypothalamus is associated with numerous functions and also controls the pituitary gland.
The hindbrain contains the cerebellum which helps control movement, posture, and balance. The midbrain and remainder of the hindbrain consists of the brain stem which controls autonomic functions such as the beating of the heart and breathing. These are functions that the body automatically does without a person having to consciously think about it.
