The behavioral term used to describe the physiological reactions to a stimulus is called a conditioned response. The word I and many other’s use for the stimulus is a “trigger.” When an event results in an uncomfortable physiological reaction something “triggers” you. Now I use “trapped emotion” instead of conditioned response but, as far as I am concerned, the words are interchangeable. The primary difference in my thinking, is that I always believed that the conditioned response was located in the brain under the skull. Trapped emotions can be located in any part of the body and are potentially responsible for a litany of physical ailments that can result from emotions being trapped in the body.
