The new device that (N) has constructed. He believes it is to be used with humans, possibly attached to the head in some way.
Is this correct?

From Thomas

That is correct (N), You will know how to wire it up and attach it to the head. It is for general healing. Try it and record feedback. Don’t spend too much time on it at the moment. It is for you and (M) to try – it could be helpful for your condition.

You both should try it though, it should help with many conditions.
