It doesn't take much to look up something and use the meaning of the word the right way in reagrds to a fictional story that one is trying to tell. It actually shows good writing to do such a thing, but since we're talking about Slott here perhaps all that goes flying out the window.
If one looks up brainwaves it should be quite clear that such a thing shouldn't be shown to have transferred the personality from one person to another and vise versa as Slott did in his story since going by the very definition brainwaves don't contain the personality the consciousness does.
