The Brain

• brain contains billions of interconnected neurones that controls complex behaviour
• 3 parts of the brain?

  Cerebral cortex, cerebellum, medulla .
• what is the cerebral cortex?

  outer part of the brain

  
• what is the functions of cerebral cortex?

  language, memory, consciousness
• what is the cerebellum?

  controls our balance and coordinates our movements like sleeping exercising

  A) Cerebellum

  
• what is the medulla?

  controls the unconscious parts like heart rate and breathing rate

  A) Medulla

  
• why is the brain difficult to treat?

  1. brain is protected by the skull so its hard to access.
  2. structures of the brain are extremely complex
  3. difficult to work out exactly which parts of the brain carry out specific functions
  4. extremely delicate and can easily be damaged
• 3 ways to investigate the brain:

  1. looking at people who suffered from brain damage
  2. electrically stimulation
  3. MRI scans
• by looking a brain damaged person, it can be easy to link how each parts of the brain function
• sticking a needle into the brain tissue to look at the active parts of the brain to look at the effects on the person's behavior
• MRI scanning is used to look at which parts of the brain are most active during activities such as listening to music or remembering things
