This study challenges the notion of sleep as a state of disconnection from the environment by investigating behavioral responsiveness in napping participants (narcoleptics and healthy volunteers) during a lexical decision task. Accurate behavioral responses, measured via facial muscle contractions, were observed across most sleep stages (excluding slow-wave sleep in healthy volunteers). Responses were more frequent during high cognitive states (indexed by prestimulus EEG). This suggests transient windows of reactivity to external stimuli during sleep, even in healthy individuals, potentially enabling real-time communication with sleepers.
