Reactivating positive memories during non-REM sleep can weaken the recall of associated negative memories. This sleep-based technique, known as targeted memory reactivation (TMR), involves presenting auditory cues linked to positive experiences during sleep, leading to a reduction in negative memory recall and an increase in spontaneous positive memory intrusions. The findings suggest potential applications for TMR in managing distressing memories and enhancing emotional well-being.
Reactivating positive memories during sleep weakens negative memory recall
Researchers have developed a noninvasive sleep intervention to weaken aversive memories by reactivating positive interfering memories during non-REM sleep. Participants first formed associations between neutral cues and negative images, followed by associations between the same cues and positive images. During subsequent sleep, auditory cues linked to these memories were presented. This targeted memory reactivation led to reduced recall of negative memories and increased recall of positive ones, suggesting potential therapeutic applications for managing distressing memories.

Sleep could help erase bad memories: ‘Therapy for our emotions’
A study from the University of Hong Kong suggests that sleep can aid in diminishing negative memories through targeted memory reactivation (TMR). By reactivating positive memories during sleep, the emotional impact of negative experiences can be reduced, offering a potential non-pharmacological approach to treating conditions like PTSD and depression.

Modifying memories during sleep could reduce trauma
Research indicates that targeted memory reactivation (TMR) during sleep can alter memory consolidation processes, potentially reducing the emotional impact of traumatic memories. This technique may lead to new therapeutic strategies for individuals suffering from trauma-related disorders.
Sleep’s secret power: Blocking unwanted memories
A study published in the Proceedings of the National Academy of Sciences reveals that sleep plays a crucial role in preventing intrusive negative memories. The findings highlight the importance of sleep in emotional regulation and suggest that enhancing sleep quality could be beneficial for mental health.
