Another study, this time from the Universiteit van Amsterdam, demonstrates that memories – most particularly long-term fear memories – are encoded when they first happen and then again whenever we re-store those memories. There is a short period of time in which the brain must chemically “prepare” and then “store” the memory. Whenever we bring the memory back to mind, it must go through the same process to re-store it in the brain. In both of these labile phases, the memory is vulnerable to change.
This research strongly suggests that memories are not, therefore, permanent structures in the brain. Their emotional content can be removed by interrupting the labile phase of long-term memory storage.
I wrote about the brain’s file cabinet in another post (Click here to read). Basically, the brain requires a chemical to access memories and to code them back after accessing them. It’s as though we take each memory, like a file, out of the long-term memory cabinet, close the cabinet, look at the file, use it, then open the cabinet again to put the file back in. If I understand Kindt’s research correctly, interrupting that process at the “putting back in” phase can, in theory, stop the perpetuation of the effects of fear memories by eliminating the fear in the memories.
