The cerebellum monitors and regulates motor behavior, particularly automatic movements. It contains more neurons than the rest of the brain and is a site of neurogenesis.
The cerebellum monitors and regulates motor behavior, particularly automatic movements. Some recent studies have associated the cerebellum with cognitive functions, such as learning and attention. Although the cerebellum accounts for roughly 10% of total brain weight, it contains more neurons than the rest of the brain combined. The cerebellum is also one of the few mammalian brain structures where adult neurogenesis (the development of new neurons) has been confirmed.

The basal ganglia comprise a group of structures that regulate the initiation of movements, balance, eye movements, and posture.
Professor Fred Gage explains that neurogenesis is an unstable process and is highly regulated by the environment.
The primary motor cortex is critical to initiating motor movements. Areas of the motor cortex correspond precisely to specific body parts.
The brain stem consists of a group of structures, including the pons, medulla oblongata, and midbrain. It controls autonomic functions such as breathing, heart rate, and blood pressure.
Professor Fred Gage explains that neurogenesis only occurs in the hippocampus and the olfactory bulb in humans, and discusses why this might be so.
The pons is the region in the brain most closely associated with breathing and with circuits that generate respiratory rhythms.
Brain scans of close relatives of children with autism reveal clear abnormalities that parallel those seen in autism.
Mirror neurons provide an important shortcut to learning new movements.
The premotor cortex is involved in preparing and executing limb movements and coordinates with other regions to select appropriate movements.
