Introduction Central Limbic
Central

The Central Core is found in all vertebrates. Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance, sleep, and the early stage of processing sensory information.


The Medulla is the center for breathing, waking, sleeping, and beating of the heart.

The Pons triggers dreaming and waking from sleep.

The Reticular Formation signals the cerebral cortex to attend to new stimulation and to remain alert even during sleep.

The Thalamus begins the process of interpreting sensory information. It determines fundamental properties, such as whether something is good or bad, and then forwards the information to the appropriate area of the cerebral cortex, where information processing continues.

The Cerebellum coordinates body movements, controls posture, and maintains equilibrium.

Research in Action:

Why do we sleep? What happens in the brain during sleep? What are the consequences of missing sleep? This daily part of life is a popular research subject among psychologists today. Certain structures from the brain's central core, including the thalamus and reticular formation, may play a key role in sleep and wakefulness.
