A brain region is also not anything close to a mechanism- you don't seem to understand what I mean by "mechanistic explanation."

I am an academic PI, and my research on brain energy metabolism is close enough to what we are talking about here that I don't need to look on wikipedia to tell you our current level of understanding doesn't offer anything close to a mechanistic explanation for experiences like this.

Some of my research has been inspired by thinking about peoples surprising anecdotal experiences and stories- and then investigating what that might imply about the underlying biology.

You seem to subscribe to a kind of scientism where genuine scientific curiosity and frank discussion about the gaps in our understanding is unacceptable. Your combination of being completely ignorant and condescending at the same time is awful.
