the brain

• the parts of the CNS are the brain, spinal cord, and nerves
• the brain is made up of billions of interconnected neurones
• the brain is in charge of all complex behaviours
• the four main parts of the brain are: the cerebral cortex, the medulla, the cerebellum and the spinal cord
• the cerebral cortex controls conscious thought and movement
• the cerebral cortex controls conscious thought and movement
• the medulla regulates breathing rate and heartbeat
• the cerebellum controls muscle coordination
• the spinal cord connects the brain to nerves throughout the body
• the cerebral cortex is responsable for things like consciousness, intelligence, memory and language
• scientists study the brain by: studying patients with brain damage ; electrically stimulating the brain and through MRI scans
