Electroencephalography

Definition

Electroencephalography (EEG) is a non-invasive technique used to record electrical activity of the brain through electrodes placed on the scalp. This method helps in understanding brain function by capturing the rhythmic oscillations that occur during various cognitive and motor tasks, making it particularly valuable in assessing motor learning processes and neural control mechanisms.
