No, and No. But in another thread a couple of (what I would call) daring neuroselfpsychoanalysis experiments are being conducted:
Sounds exciting:
Anything that pertains to causes of various altered states of reality would be helpful towards computationally modeling these states of mind too.
Whether the model is as conscious as we are of itself existing is not for me a modeling issue. I don’t expect this would change behavior of systems producing a sensation of itself, in itself.
