The Thought Police could eventually exist in reality, if they can just figure out how to harness new technology developed by Japanese researchers, the Daily Yomuri reports. The team managed to re-create images that people were looking at—using only subjects' recorded brain activity. This is the first successful display of messages directly from the human brain.
The scientists recorded the patterns of neurons coming from the retina, which processes visual signals. By showing subjects test patterns of gradually increasing complexity, the team was able to map which neurons correspond to each part of the visual field. When subjects saw the word "neuron," the computers showed a fuzzy image of the same word.
