Quizplus · Accepted Answer

The injection of a radioactive substance and use of a scanner to analyze brain activity is characteristic of positron-emission tomography. Option B, functional magnetic resonance imaging, does not typically involve the use of a radioactive substance. Option C, microelectrode recording, involves using electrodes to detect electrical activity within the brain, while option D, an electroencephalogram, involves placing electrodes on the scalp to measure electrical activity in the brain. Neither of these techniques involve the use of a radioactive substance or a special scanner.
