This emotional-arousal-activated neurobiological system thus seems to play an important adaptive role in insuring that the strength of our memories will reflect their emotional significance.[These memories] feel like a bona fide representation of the past, but memories are constantly modified with new information." Extinguishing the traumatic aspect of a memory involves creating new, safer mental associations to the same sensory cues.Even long-term memories, when recalled, have plasticity and the potential to be updated, an ability psychologists co-opt during exposure therapy, in which a patient faces his or her fears in a non-threatening environment in the hope of gaining control of them."We will use both biological and neurological measures to give us clues as to treatment." Though just beginning to plumb the brain's depths, scientists have formulated some theories on how our brains process fearful memories.
First, as we witness a scary event, the thalamus relays sensory information to the amygdala, which stamps the memory as emotionally significant and stores it for future use, to help us avoid related threats.
The research began with the finding that stimulant drugs enhanced memory in rats when administered shortly after training.
