Question

Quizplus · Accepted Answer

EEG (electroencephalography) involves placing electrodes on the scalp to measure the electrical activity generated by the brain.

Answer: A
 fMRI (functional magnetic resonance imaging) uses magnetic fields to measure changes in blood oxygenation levels in the brain, which can indicate which areas of the brain are active during a particular task.

Answer: B
 PET (positron emission tomography) involves injecting a radioactive tracer into the bloodstream and measuring the resulting gamma rays emitted from brain cells. This provides information on brain metabolism and activity.

Answer: D
 MRI (magnetic resonance imaging) uses magnetic fields to create detailed images of brain structure and tissue.

Answer: E
 TMS (transcranial magnetic stimulation) involves using a magnetic coil to stimulate or inhibit neural activity in a specific area of the brain. It is not a recording method, but rather a method for manipulating brain activity.
