This pretty well explains why planned substitution therapy is sopromising. One establishes what the triggers are and then associatealternative thoughts to weaken the original memory which in PTSDcases are debilitating.
I will leave how up to the imagination of the therapist.
The point here is that there is a clear physical pathway involvedthat confirms what has already been observed in therapy and supportsongoing effort that plausibly needs to be continuing. In fact aprogressive protocol is strongly indicated as a brain managementtool.

Many of us probably have memories wewould like to forget. If that includes you, I have some good news —researchers have discovered two ways we can make our own brains erasememories.
Researchers from the University ofCambridge published a study of these two ways in a paper today,Oct 17, in the journal Neuron.
"This study is the firstdemonstration of two distinct mechanisms that cause such forgetting:one by shutting down the remembering system, and the other byfacilitating the remembering system to occupy awareness with asubstitute memory," study researcher Roland Benoit saidin a statement from the journal.
The researchers studied 36individuals that were asked to remember word pairs like "beachAfrica." They were then told to forget the word pairs using oneof two methods: Half the participants were told to just forget theword "Africa" while and the other half were supposed tosubstitute "Africa" for the word snorkel.
The researchers scanned theparticipants brains using a functional MRI to measure brain activitywhile they were actively forgetting. They found different,distinct brain activity for the two different forgetting approaches.
During direct suppression — active forgetting — a brainstructure called the dorsolateral prefrontal cortexinhibits activity of the hippocampus, an area involvedin memory forming, organizing, and storing.
During thought substitution —thinking "snorkel" instead of "Africa" — thebrain's remembering power (controlled by two spots in the brain thatcall attention to the thing you are trying to remember) is splitbetween the two words, so it had trouble recalling "Africa"later.
These mechanisms both impairremembering and weaken traces of the unwanted memory. Theseapproaches may help develop new treatments for things likepost-traumatic stress disorder. For example a therapist could workwith a shaken soldier to dampen the traumatic memories.
