EMDR (Eye Movement Desensitization and Reprocessing) developed by Francine Shapiro to change neural memories from negative events, PTSD and other types of trauma. It uses alternating bilateral visual, tactile or auditory stimulation such as watching a light move back and forth. This is done while holding a distressing image or memory in mind. It activates a memory chain related to the event. This softens, or deactivates, the triggering aspects of a memory to create a sense of resolution and safety.
