Discussion

Experiment reveals shared neural signatures of emotionality in sleep, indicating potential for PTSD and depression treatment.

Detection of emotionality occurred 0.4-0.6 seconds post cue during sleep, showing reactivation effectiveness.
Classifier trained on EEG data accurately identified emotional memories linked to auditory cues.
Employing a machine learning pipeline without individual fine-tuning enables efficient analysis across participants.
Findings suggest methods for leveraging sleep reactivation could aid in long-term emotional memory restructuring.

Abdellahi et al. (2025) studied this question.
