Historically, sleep studies have been done by a combination of electroencephalography (EEG) and electromyography (EMG), the signals obtained allowed to define three sleep/wake stages(REF). The first one is displayed by awake animal, the EEG show a high frequency activity (beta waves) and the EMG signal is high, reflecting the motor activity of the animal. The second and third stages are present in sleeping animals, called respectively non-rapid eye movement…
