I don't think such an advance leap in neuro surgery will be available to the public in two years. It actually involves grafting a brain with the brain stem to another body with a preexisting working nervous system. This tech would involve neural grafting, neural regeneration and neuro surgery so advanced that we should just ne in star wars. If they dix have this tech then we should've had a cure for other neuro degenerative diseases such as Parkinson's.
I can't point out what but you seem to be confused about this idea. It doesn't involve neurosurgery or brain cell grafting, even though I don't know what the latter would mean in practice. In simple terms, the idea discussed here is about attaching someone's head to someone else's body. Technically, it is quite feasible, albeit the person whose head gets transplanted in this way won't feel his new body. This is the major problem.
