AP psych brain scanners

CT scan

Uses X-rays token from multiple angles to create images of the brain structure

MRI scan

Uses strong magnetic fields/radio waves to produce very detailed images of the brains anatomy

FMRI scan

Measures how much oxygen blood cells have to see where increased activity lies

PET scan

Uses radioactive glucose to track where the glucose accumulates

EEG

Purs electrodes on the scalp to measure electrical activity generated by populations of nuerons
