Structure of the brain

Corpus Callosum

The Corpus Callosum are axon fibers connecting the two cerebral hemispheres.


The thalamus is the brain's sensory control center located on top of the brainstem. It directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla


A neural structure lying below the thalamus. It directs several maintenance activities. These include eating, drinking, and body temperature.

Pituitary Gland

Master of endocrine gland. The pituitary gland regulates growth and controls other endocrine glands. The pituitary gland is controlled by the hypothalamus.

Reticular Formation

The reticular formation is a nerve network that travels through the brainstem and thalamus. Helps control arousal (sleep/wake)


Helps coordinate movement.


Controls heartbeat and breathing. Keeps you alive.

Spinal Cord

The spinal cord is the pathway for neural fibers traveling to and from the brain. It also controls the simple reflexes.


The cerebellum coordinate voluntary movement and balance and supports learning and memories such.


The amygdala is linked to emotion, specifically anger.


The hippocampus is linked to memory.

Cerebral Cortex

The cerebral cortex is the ultimate control and information-processing center.
