The role of the right VLPFC is only found by the depersonalization research unit in samples of brain scan other researchers says is to small in size and increases the chances of error. The rTMS was only of 8.patients and not placebo controlled. Others have not supported the role of the right VLPFC but others point more towards the anterior cingulate and the dorsomedial prefrontal. The anterior cingulate and the dorsomedial prefrontal cortex also came out as abnormally active in the depersonalization research units brain scans along with the right VLPFC. Both locations could play a central role. In 2014 is was not technically possible to intervene at the anterior cingulate and the dorsomedial prefrontal as they are to deep. They only had a coil the that go 1.cm into the brain. So, to intervene at parts the right VLPFC was the only option they had for a trial back then. Because there is a very strong obsessive compulsive component in depersonalization of self awareness and monitoring that is very OCD like the activity of the anterior cingulate and dorsomedial prefrontal cortex might be central.
in medicine in general there is a replication crisis. Findings or trails can not be replicated by others in 50% of the cases. In depersonalization research it is likely a similar figure because the trails have often been very small and not placebo controlled. The samples sizes in brain scan are also very small and increases the chances of errors. So, you have to read everything with some moderation and this in mind.
