A research team at the ATR Computational Neuroscience Laboratories in Japan has successfully displayed simple images produced in the human brain on a computer screen. Dream recorder anyone? In a nutshell, the device converts electrical signals sent to the visual cortex into images that can be viewed on a computer screen. In their experiment, they showed test subjects the six letters in the word neuron and succeeded in reconstructing the word on screen by measuring their brain activity. As the technology progresses, it could be possible to “see” what people are thinking, what they dream about and record it for posterity.
Personally, I’d be curious to see my own dreams, if they could be recorded (I don’t often remember my dreams unless they’re really significant or vivid); but the concept of others watching/recording thoughts or dreams is kind of creepy.
