the brain

• Brain


  Made up of billions of interconnected nerve cells, holds all of our thoughts and memories, responsible for complex behaviors
• Brain regions


  • Cerebral cortex/cerebrum
  • Cerebellum
  • Hypothalamus
  • Brain stem/medulla
• Cerebral cortex/cerebrum


  • Responsible for consciousness, intelligence, memory, language, vision, hearing
• Cerebellum


  • Responsible for controlling balance and muscle coordination
• Hypothalamus


  • Involved in regulating body temperature and sending signals to the pituitary gland
• Brain stem/medulla


  • Controls unconscious activities like breathing and heartbeat
• How scientists study the brain

  1. Study people with brain damage

  2. Electrically stimulate different parts of the brain

  3. Use brain scanning techniques (CT, PET, MRI)
• CT scans are mainly used for seeing which areas of the brain are damaged
• PET and MRI scans are better at measuring the underlying activity of the brain
• The brain is difficult to treat due to the wide range of things that can go wrong, it being encased in the skull and fragile brain tissue, and the brain's complexity
