Have you heard of the Adaptive Information Processing (AIP) model utilized to describe EMDR? With AIP the basis of clinical pathology is hypothesized to be dysfunctionally stored memories, with therapeutic change resulting from the processing of these memories within larger adaptive networks. Unlike extinction-based exposure therapies, memories targeted in EMDR are posited to transmute during processing and are then again stored by a process of reconsolidation.

Here are some new ideas:

It seems a good idea of research but I would begin from the origin to the recent reserches. I could suggest: from Freud to Boris Cirulnik who speak French and is very rewarding to listen. There is also EMDR studies as it is remembered here. But a organic complex vision is more useful. By the way, from Ferenzi to Masud Khan the continuative trauma concept has been developed.
