Exposure to extinction-associated contextual tone during slow-wave sleep and wakefulness differentially modulates fear expression

Recent research has used context cues(odor or auditory cues)to target memories during sleep and has demonstrated that they can enhance declarative and procedural memories.However,the effects of exter-nal cues re-presented during sleep on emotional memory are still not fully understood.In the present study,we conducted a Pavlovian fear conditioning/extinction paradigm and examined the effects of re-exposure to extinction memory associated contextual tones duringRecent research has used context cues(odor or auditory cues)to target memories during sleep and has demonstrated that they can enhance declarative and procedural memories.However,the effects of exter-nal cues re-presented during sleep on emotional memory are still not fully understood.In the present study,we conducted a Pavlovian fear conditioning/extinction paradigm and examined the effects of re-exposure to extinction memory associated contextual tones during中国睡眠研究会
