Positron emission tomography, or PET scan, involves injecting a radioactive substance into the body and then using a scanner to detect the radiation given off as it moves through the body. By using a glucose-like substance, doctors can analyze the biochemical activity in the brain. This technique is different from functional magnetic resonance imaging (B), which uses magnetic fields and radio waves to image brain activity. Microelectrode recording (C) involves inserting electrodes into the brain to record the activity of individual neurons, and an electroencephalograph (D) measures electrical activity on the scalp.
