Japanese Scientists have managed to figure out how to capture images from a person's mind and reconstruct them into a form that is recognizeable on a computer screen. The article I read has the following:
...by using a functional magnetic resonance imaging machine the researchers were able to map blood flow changes within a human brain's cerebral visual cortex when exposed to specific control images. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each, which allowed the scientists to map the changes associated with images, essentially calibrating the machine. Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the machine was able to recognize and reconstruct the images in a recognizable, all be it low-res image.
So far, the system can only recognize simple, black and white images, but scientists are confident the technology will advance so much in the next 10 years that reading a person's mind with some degree of accuracy will be possible. This technology could be used in the fields art and design; imagine being able to see the images inside an artists head! It could also be used to treat mental conditions that exhibit hallucinations, allowing doctors to see exact what their patients think they're seeing. ATR chief researcher Yukiyasu Kamitani says, “This technology can also be applied to senses other than vision. In the future, it may also become possible to read feelings and complicated emotional states.”
My take? It's a small step from reading minds to implanting thoughts and images into them. It's a technology like anything else: not evil or good by nature. It is how it is used at to whether it's good or bad.
