As interesting as the video is, there are some fatal flaws in the design of the experiment. The first, and possibly most important point is this:

"..a woman stimulated herself inside an fMRI machine."

However she got to orgasm, you are simply seeing the moment of the event, not all the rest you are talking about. The issue is the way the brain pulls in parts of itself at that moment. Recruitment, recruitment with neurons firing and synapses being filtered and monitored. Signals expessed and supressed. It is studies like this that make me believe AI will aways be AI and Brain-I will always be different and never computer attainable.
