Question

Quizplus · Accepted Answer

Electroencephalography (EEG) is a noninvasive system for studying brain activity by attaching electrodes directly to the scalp to measure electrical activity produced by the brain. Event-related potentials (B) are a type of EEG that measures electrical activity specifically related to sensory, cognitive or motor events. Microelectrode recording (C) is an invasive technique that involves inserting an electrode into the brain to record from individual neurons. Electromyography (D) is a technique used to measure electrical activity produced by muscles.
