B10.4 | Brain labelling and knowledge test | (GCSE AQA Triple Biology)

A = Cerebellum - controls coordination of muscles 

B = Medulla - control unconscious activities, such as heartbeat and breathing.

C= Cerebral cortex - is concerned with consciousness, intelligence, memory and language

• 1) What is the brain made up of? [2]
• 2) How can scientists map reigons of the brain? [3]
• 3) What are the problems with studying the brain? [3]

• 1) The brain is made up of billions of neutrons that are all connected [1] and control the complex human body and behaviour [1]
• 2) Scientists can map the brain by: 
  • Studying patients with brain damage [1]
  • Electrically stimulating different parts of the brain [1]
  • Using MRI (Magnetic Resonance Imaging) scanning techniques to monitor brain activity when doing certain activities [1]
• 3) Problems with the brain:
  • Surgery with the brain is difficult because the brain in protected by a very thick and hard skull. [1]
  • Special drugs cannot get into the brain or pass through the membranes surrounding the brain [1]
  • The function of each area of the brain is not fully understood. [1]
