So, what role does memory play in the understanding and treatment of trauma? There is a form of implicit memory that is profoundly unconscious and forms the basis for the imprint trauma leaves on the body/mind. The type of memory utilized in learning most physical activities (walking, riding a bike, skiing, etc.) is a form of implicit memory called procedural memory. Procedural or “body memories” are learned sequences of coordinated “motor acts” chained together into meaningful actions. You may not remember explicitly how and when you learned them, but, at the appropriate moment, they are (implicitly) “recalled” and mobilized (acted out) simultaneously. These memories (action patterns) are formed and orchestrated largely by involuntary structures in the cerebellum and basal ganglia.When a person is exposed to overwhelming stress, threat or injury, they develop a procedural memory. Trauma occurs when these implicit procedures are not neutralized. The failure to restore homeostasis is at the basis for the maladaptive and debilitating symptoms of trauma.
