Question

Quizplus · Accepted Answer

EEG recordings primarily reflect the activity of cells near the surface of the brain. The electrical activity generated by these cells can be detected through the skull and scalp, but the signals are attenuated as they pass through deeper brain structures. Therefore, EEG recordings are most sensitive to the activity of cells near the surface of the brain.
