Who doesn't support stuffing circuitry inside people's skulls to ensure they only think Goodthink? MIT's got a grant to dust off the 40-year-old research (PDF) and get it running. From the horse's, er, whatever:
Darin Dougherty, a psychiatrist who directs Mass General’s division of neurotherapeutics, says one aim could be to extinguish fear in veterans with post-traumatic stress disorder, or PTSD. Fear is generated in the amygdala—a part of the brain involved in emotional memories. But it can be repressed by signals in another region, the ventromedial pre-frontal cortex. “The idea would be to decode a signal in the amygdala showing overactivity, then stimulate elsewhere to [suppress] that fear,” says Dougherty.Where's that line to sign up?
Also, consider, “The idea would be to decode a signal in the amygdala showing overactivity, then stimulate elsewhere to [suppress] that fear,” and ask yourself what other military applications there might be for fear-suppressing brain machinery.
It's a helluva a world. I may have another 30 or 40 years in it and I've stopped looking forward to them. Fearless brain-wired solders are only one of the more obvious little clouds on the horizon.
