Question

Quizplus · Accepted Answer

The technique described in the scenario, involving the injection of a radioactive glucose-like substance and a scanner to measure biochemical activity in the brain, is consistent with positron emission tomography (PET) imaging. Functional magnetic resonance imaging (fMRI) does not involve the injection of radioactive substances and instead measures changes in blood flow in the brain, while microelectrode recording and electroencephalogram (EEG) involve the use of electrodes to directly measure electrical activity in the brain.
