Maybe someone has mentioned EMDR and piqued your interest. Maybe you came across it while searching for answers to whatever has been ailing you. Eye movement desensitization and reprocessing does not roll off the tongue easily. It sounds more technical than it does like a healing journey. But if you are living with the weight of trauma, you are probably less focused on the name and more concerned with whether the method actually works.
Understanding what is happening in your brain during EMDR can make the process feel a lot less intimidating. The neuroscience behind it is quite fascinating and should reassure you that healing is possible.
When Trauma Gets Stuck in the Brain
When you experience an overwhelming situation, like trauma, your brain is not always able to process all the details. Under extreme stress, your amygdala, which is your brain’s built-in alarm system, goes into overdrive. Your hippocampus, the part responsible for storing your memories, then struggles to do its job effectively. Ultimately, traumatic memories can get stuck in an unprocessed space, continuing to cause problems in your current life.
This is why trauma feels like it stays with you. These “stuck” memories should be left in the past. Instead, they create vivid images, imprinted on your brain that leave you feeling threatened long after the danger has passed. Certain sounds or smells can instantly trigger an intense emotional or physical response because the brain never fully closed the loop.
What EMDR Does Differently
During your REM sleep cycle, your system naturally processes and consolidates the happenings of the day. EMDR incorporates side-to-side eye movements, tapping, or auditory stimuli to activate both sides of your brain, mimicking REM sleep.
After trauma, your brain holds onto a distressing memory. Bilateral stimulation supports your brain in doing what it could not do during the traumatic event. Once you can process it and place it in the right context, the emotional charge it has been carrying will dissipate. It may not disappear entirely, but you should stop feeling like it is a live wire in your system.
Researched Brain Changes
Imaging studies have shown measurable changes in the brain following EMDR sessions. Notable findings include:
Reduced activity in the amygdala
Improved communication between the two hemispheres of the brain
Greater prefrontal cortex engagement supporting rational thinking and emotional regulation
Changes in how traumatic memories are stored and retrieved
Simply put, EMDR helps the brain reorganize itself around the trauma rather than continuing to be controlled by it.
What to Expect During a Session
If you are familiar with traditional talk therapy, this concept may be a bit shocking. Your therapist will not ask you to relive every detail of your past trauma. Instead, you will be guided to focus on a specific memory while going through the bilateral stimulation.
Sessions follow an eight-phase structure, starting with a history and grounding prepwork. The goal is to make sure you understand the process and feel safe moving forward. As you enter the bilateral stimulation phase, you may notice emotions, body sensations, or unexpected thoughts coming up. Rather than being alarmed, take it as a sign that processing is working.
Your therapist will check in frequently with you, ensuring you stay regulated throughout the session. The hope is that as you progress through your journey, the memories become less intense. This may even be noticeable in a handful of sessions, though the timeline may vary depending on the complexity of the trauma.
