What is EMDR?

EMDR, or Eye Movement Desensitization and Reprocessing, is a partially physical treatment in psychotherapy used to reduce psychological pain associated with trauma. It involves watching a light move back and forth, tapping your hands on your legs, or holding two small vibrating paddles, one in each hand, while letting your brain relive a traumatic event. The physical component (be it the moving light, the tapping hands, or the vibrating paddles), causes bilateral stimulation. When combined with the brain’s amazing ability to make sense of complicated feelings and situations, effective healing can occur.

We have two hemispheres in our brains; the right hemisphere and the left hemisphere. They are connected in the middle by a part of the brain called the corpus callosum. The corpus callosum does the job of communicating thoughts, memories, emotions, and other information between the two hemispheres. When you experience a traumatic event, your brain makes a fixed memory, including all of the physical and emotional feelings you had at that moment. This is sometimes referred to as a “flashbulb memory” (flashbulbs were used with old cameras as the necessary light source for a photo), because the image is frozen in your mind in great detail, and details will remain there, largely unchanged, for years. It is important to note that most memories are extremely flimsy and subject to change, even from hour to hour. Flashbulb memories are different. They are “stuck” in a neural memory network in a specific part of your brain and are cut off from the rest of your brain. Anything that comes in contact with this “stuck” part of your brain will be negatively affected by your trauma. The stuck trauma can cause negative thoughts, feelings, and behaviors. This is where EMDR comes in.

Bilateral stimulation means that both hemispheres are stimulated alternatingly (right brain, then left brain, then right brain, then left brain, and so on). Bilateral stimulation is the crucial element in EMDR because it aides the corpus callosum in communicating between Continue reading
