Question

Quizplus · Accepted Answer

The technique being used involves injecting a radioactive glucose-like substance and using a scanner to measure the distribution of the substance in the brain. This describes the process of positron emission tomography (PET), which can provide information about the metabolic activity of the brain. Option B (functional magnetic resonance imaging) uses a magnetic field to measure changes in blood flow to different areas of the brain, while option C (microelectrode recording) involves inserting electrodes directly into the brain to record neural activity. Option D (an electroencephalogram) records electrical activity on the scalp and would not involve injecting a radioactive substance.
