Question

Quizplus · Accepted Answer

Electroencephalography (EEG) is a non-invasive method for measuring electrical activity in the brain. EEG measures the collective behavior of neurons rather than action potentials from individual neurons. EEG is often used to record event-related potentials (ERPs), which are changes in electrical activity in response to specific stimuli. EEG cannot identify whether specific cells are active during sleep or waking, as it measures the overall electrical activity of large populations of neurons.
