cowtamer writes "CNN has a writeup on a method of treating depression with implanted electrodes. If this works, we may be seeing a lot more of this type of technology in the future. '[The patients] were lightly sedated when the holes were drilled and the electrodes implanted, but they were awake to describe what they experienced. Several patients reported profound changes just minutes after the stimulator was turned on. One said the room suddenly seemed brighter and colors were more intense. Another described heightened feelings of connectedness and a disappearance of the void.' While I haven't looked into any of the academic literature on this, it seems that yet another Larry Niven Prediction has come true!"
