Researchers in Sydney have come up with a fix for chronic pain that’s not really a fix at all: a smart chip that, when embedded in the spine, intercepts and blocks pain messages en route to the brain. …
the chip can measure the properties of signals and pick out the ones that are carrying pain to the nerve center. When it sees a pain signal headed brainward, it can send out a 10-volt electric pulse that blocks the pain signal; no signal, no pain.
Or you could flip the chip to enhance pleasure. Everyone would die happy. Sooner, yes, but very, very happy.
Or you could flip the chip to amplify pain. Now the CIA could torture you with a feather. No harm, no foul, right? John Yoo would be proud.
