Scientists from Japan's ATR Computational Neuroscience Laboratories are currently working on a technology that could be used to show images from our brains on the computer screen in the future. This technology is able to discern what a person is thinking (or dreaming) and could make an actual visual representation of it on the screen. However, the technology is still verdant and the researchers have barely scratched the surface.

In an article published in the magazine "Neuron," it was stated that the scientists performed experiments on people by showing them 400 different still images and determining brain patterns while the people look. One notable part of the experiment was when the subjects were shown the word "neuron" and the letters were successfully reconstructed onscreen from their thoughts. While I'm sure it will be an amazing technology, I dread the day when even sleeping could be risky because someone could tap into your brain.
