Are there known neuronal mechanisms that somehow explain phenomena like
i.e. deviating-from-normal experiences and beliefs about one's thoughts (where they come from, where they go to)?
Some references would be great.
Edit: A famous example of thought insertion (or auditory hallucinations - who would tell the difference?) has a Wikipedia article on its own: A course in miracles by Helen Schucman (whose brain presumably has not been investigated).
