Temporoparietal junction:
Temporal lobe
parietal lobe
junction: where they meet
in other words, around the ear section- a bit to the back.

about the perspective thing: From what I read in the paper, the effect of autoscopy: auto-self, scope- to see
is that you're seeing yourself from your own body, not experiencing being out of body. Like looking in the mirror. Like seeing a reflection/projection of yourself.
Most of these people were experiencing autoscopy, not experiencing the sensory perception of being the reflection.
Even though OBE can have a variety of, well, variety, these people were essentially having the same experience, very limited in symptoms.
So in my opinion, the symptoms were not close to what we call OBE here to call it the same thing.
That's all I'm saying.
I left all the metaphysical stuff out of the critique (the mind-soul connection) because I was inspecting the scientific part of the theory behind the study, and I found it lacking.
