General anesthesia is defined as a drug-induced reversible condition composed of unconsciousness, amnesia, analgesia, immobility and stability of the autonomic, cardiovascular, respiratory and thermoregulatory systems. Monitoring behavioral states during general anesthesia is challenging. During general anesthesia, amnesia is not monitored directly but implicitly by the extent to which unconsciousness is achieved.
