Our memories are in-part reconstructions. Whenever we retrieve a memory, the brain rewrites it a bit, updating the past according to our present concerns and understanding. At the cellular level, retrieving a memory means it will be reconsolidated and slightly altered chemically by a new protein synthesis that will help store it anew after it has been updated. Each time we bring a memory to mind, we adjust its very chemistry; the next time we retrieve it, that memory will come up as we last modified it. The specifics of the new consolidation depend on what we learn as we recall it. If we merely have a flare-up of the same fear, we deepen our fearfulness. But the high road can bring reason to the low. If at the time of the fear we tell ourselves something that eases its grip, then the same memory becomes re-encoded with less power over us. Gradually we can bring the once-feared memory to mind without feeling the rush of distress all over again” says Joseph le Doux, a neuroscientist at the Center for Neural Science at New York University. Therefore, it is possible to acquire the skills of nervousness control and with practise release the fear altogether.
