Can we currently activate the pleasure center non-invasively? The only experiments I've heard of this have been invasively on rats and a few humans.

  Some of the deep brain stimulation research is focused on using a carefully constructed magnetic fields such that they can create a 'node' at any point inside the skull. Then by modulating that node create an electrical current using the available ions. I have no idea if that will be a fruitful path for them but it has the 'feature' that it can act in any part of the brain.

    Interesting - this? http://en.wikipedia.org/wiki/Deep_transcranial_magnetic_stimulation http://en.wikipedia.org/wiki/Deep_transcranial_magnetic_stim... I hadn't seen this before. Very cool!

      Yup. Still challenging to get it to narrow areas.

    Inducing current in the brain in this manner requires very strong magnetic fields.

      Not particularly strong fields, you're not flipping water molecules like you are with CAT scan, and the point was that it can stimulate interior nodes of the brain without physically putting wires there.
