PRESENTATION OF THE SIGNALS

electromyography
measures the electrical activity of muscles through electrodes placed on the muscle to explore.
electroencephalogram
measures the electrical activity of the brain through electrodes placed on the scalp.
Electrocardiogram
measures the heart's electrical activity through electrodes placed on the limbs or chest.
