What are the two tools researchers use to understand the structure/anatomy of the brain?
Lesion Studies - Naturally or surgically caused destruction of a small amount of the brain
MRI - Uses a magnetic field to align the spinning atoms of brain molecules
What are the two tools researchers use to understand the functioning of the brain by
examining external electrical activity?
EEG - Records electrical activity produced my neurons firing. Measured via electrodes on the scalp
MEG - Records magnetic fields produced when neurons fire
Which two allow researchers to measure internal brain activity?
FMRI - Measures blood flow to the different areas of the brain. Shows brain structure and function
PET - Measures glucose consumption by different areas of the brain. Requires injecting the person with radioactive glucose
