Thought experiment. If they got accurate Deep Brain Stimulation to work - would you use it? http://is.gd/f4eW- (Syndicate style?)
I always pondered - would there be a way to stimulate specific parts of the brain if you had orthogonal stimulators? One one side, another 90 degrees to it?
And if you could successfully do implants, why not? Or go through the nasal cavity, or the ears?
I remember the Royal Society had a small spot on one of theire open science days. There is a fair bit out there, of what happens when you stimulate neurons, and to behonest, it sounds like if you could do it accurately, it'd be bloody good fun, and highly addictive.
