Computational Neuroscience: All we've ever dreamed of

For the first time ever, scientists were able to produce images directly from brain activity. The team created a device that captures electrical signals and interprets them just as the visual cortex of the brain does.

The Japanese researchers showed testers the six letters of the word "neuron", and successfully measured their brain activity to reconstruct the letters on a computer screen. The test confirms that ATR Computational Neuroscience Laboratories is just steps away from being able to replay dreams we've had, further unlocking mysteries of how dreams work and opening doors to new methods in clinical psychology.

Dreams are interesting, but what about the problems it would solve in communication? Think of all of the times you have thought or said, "I can see it in my head but can't draw or describe it." Whiteboards and long-winded explanations could be replaced by projectors feeding from your visual cortex. Now that would be awesome.

Any other ideas?
