But what actually happens in this flashbulb moment? How does a flashbulb moment seem to collide with a long exposure, something that we know to be impossible? Two small portions of our brain known as the amygdalae – groups of hyper-responsive nerve bundles in the temporal lobe concerned primarily with memory and decision-making – commandeer the rest of the brain’s functions to react in a crisis. It is something that seems to stretch a one-second fall to five seconds or more, set off by fear and sudden shocks that hit our limbic system so hard that we may never forget them. But our perceived duration distortion is just that; clock time has not in fact offered to pause or elongate for us. Instead, the amygdalae have laid down memories with far more vivid detail, and the time distortion we perceive has just happened in retrospect. The neuroscientist David Eagleman, who has conducted many experiments into time perception and as a boy experienced a similar elongation of time when he fell off a roof, explains it in terms of ‘a trick of the memory writing a story of a reality’. Our neural mechanisms are constantly attempting to calibrate the world around us into an accessible narrative in as little time as possible. Authors attempt to do the same, for what is fiction if not time repositioned, and what is history if not time in retrospect, events re-evaluated in our own time?
