Unit 2: Part 1C: How to Study the Brain

Question 1

Electroence Phalogram

Answer 1

EEG; a noninvasive test that records electrical patterns in your brain with electrodes placed on the scalp; measures brain activity

Question 2

Magnetoence Phalography

Answer 2

MEG; uses over 300 highly sensitive sensors that detect magnetic fields that are produced from the electrical activity in the brain

Question 3

Computed Tomography Scan

Answer 3

CT Scan; x-ray photographs takes from different angles combined by computer to show a sliver of the brain’s structure

Question 4

Positron Emission Tomography

Answer 4

PET; helps doctors see how well organs and tissues are functioning; a visual display of brain activity that detects where a radioactive glucose goes while the brain performs a given task; shows activity

Question 5

Magnetic Resonance Imaging

Answer 5

MRI; uses magnetic fields and radio waves to create images of the brain; shows brain anatomy

Question 6

Functional Magnetic Resonance Imaging

Answer 6

fMRI; a measure of blood flow and brain activity by comparing successive MRI scans to show brain function as well as structure; used when patients perform a certain task
