One of the effects of the adrenal rush is that our high- or conscious- brain essentially shuts down and turns most operations over to the lower brain. That is why we have a hard time thinking and solving simple issues and problems under adrenal stress. The higher the stress level, the less conscious thought we have. However, one of two things happens in this state: We either have very little or no recollection of the event, or we retain a complete and detailed recollection of the event. This varies by individual and intensity of the event. What’s important is that while under this state it is hard to think, which is good, because we usually don’t have time to think – we need to react.
