The experiment was conducted over three days: the memory was formed in the first day, rewritten on the second day, and tested for fear on the third day. However, to examine how enduring this effect is, a portion of the participants was tested again about a year later. Even after this period of time, the fear memory did not return in those subjects who had extinction during the reconsolidation window. These results suggest that the old fear memory was changed from its original form and that this change persists over time..."NYU Researchers Develop Non-Invasive Technique to Rewrite Fear Memories"
"Our research suggests that during the lifetime of a memory there are windows of opportunity where it becomes susceptible to be permanently changed," said (post-doctoral fellow Daniela) Schiller. "By understanding the dynamics of memory we might, in the long run, open new avenues of treatment for disorders that involve abnormal emotional memories."
