Introduction: The inability to extinguish a conditioned fear is thought to be at the core of post-traumatic stress disorder. Eye movement desensitization and reprocessing therapy has been efficacious for post-traumatic stress disorder, but the brain mechanisms underlying the effect are still unknown. The core effect of eye movement desensitization and reprocessing therapy seems to rely on the simultaneous association of bilateral alternating stimulation and the recall of the traumatic memory…

An Efficient System for Eye Movement Desensitization and Reprocessing (EMDR) Therapy: A Pilot Study
An actuator-based EMDR (eye movement desensitization and reprocessing) virtual assistant system that can be used for the treatment of participants with traumatic memories, including an artificial intelligence chatbot capable of acting autonomously is described.

This review presents the current state of understanding of trauma-informed modalities in light of current research in neuroscience, analyzing which brain structures and processes are impacted by


Facilitating Access to Emotions: Neural Signature of EMDR Stimulation
First time evidence for a putative neurobiological basis of the bilateral alternating stimulation as used in the EMDR method is demonstrated, showing an increase in limbic processing along with decreased frontal activation in line with theoretical models of how bilateral alternating stimulating could help with therapeutic reintegration of information.
Fear extinction learning improvement in PTSD after EMDR therapy: an fMRI study
Functional modifications underlie a significant improvement of fear extinction learning in PTSD patients after EMDR therapy.
Bilateral Alternating Auditory Stimulations Facilitate Fear Extinction and Retrieval
The results demonstrate the importance of BLS to reduce negative emotions, and provide a successful model to further explore the neural mechanisms underlying the sole BLS effect in the EMDR.

Eye Movement Desensitization and Reprocessing for Posttraumatic Stress Disorder: A Pilot Blinded, Randomized Study of Stimulation Type
There are clinically significant effects of the EMDR procedure that appear to be independent of the nature of the kinesthetic stimulation used, however, alternating stimulation may confer an additional benefit to the EM DR procedure that deserves attention in future studies.

Disruption of Reconsolidation Erases a Fear Memory Trace in the Human Amygdala
As previously demonstrated in rodents, fear memory suppression resulting from behavioral disruption of reconsolidation is amygdala-dependent also in humans, which supports an evolutionarily conserved memory-update mechanism.
