Hypnosis is a Conversation. Knowledge of neurology doesn’t make me, or anyone else, a better hypnotist. In …fact I’d go so far as to suspect that makes one a worse one because the focus is on physicality rather than psychology where it should be.
To use a metaphor or analogy that is better understood, Hypnosis deals with the conversation and the emotional processing of the content of the conversation when people talk to each other over a mobile phone.
It is not about how the network works, or how the phones themselves work. And focusing on that takes away from the conversation.
