Correcting memory errors


A traumatic event may be accompanied by the memorization of a trivial occurrence at the same time, which will then, once associated, be capable of triggering stress and anxiety alone, even in the absence of the traumatic event. This type of non-associative memorization is a source of post-traumatic stress and pathological anxiety.
However, researchers have shown in the invertebrate aplysia that non-associative memory is chemically different from normal memory and that it is possible to erase it without erasing the memory of the event.
This fundamental discovery, must be consolidated in other models, but allows us to envisage a way to treat certain situations-base pathological stress.
