Measuring the Brain

Question 1

What is an EEG?

Answer 1

- This records WHEN electrical activity in the brain occurs

Question 2

What is an MRI?

Answer 2

• Magnetic Resonance Imaging
• uses magnetic fields
• shows brain’s structure and abnormalities

Question 3

  oxygen
• used to determine if someone is aware but not
  conscious by asking questions and comparing brain
  activity to that of a normal person

Question 4

What is a PET scan?

Answer 4

• Position Emission Tomography

- Measures blow flow to active areas of the brain by tracking radioactive oxygen or glucose that is injected

Question 5

What is the invasive technique electrophysiology?

Answer 5

The study of electrical activity in the body

Question 6

Answer 6

This measures neurotransmitters released in the brain

Question 7

What is the invasive technique lesioning?
