Technology to Visualise the dreams.

There was a time when we used to think about visualising about the dreams of other people or what they are thinking in thier mind. sounds like fictious but japanese researchers have made it true to some extent.
Researchers at the ATR Computational Neuroscience Laboratories succeeded in processing and displaying images directly from the human brain, they said in a study unveiled ahead of publication in the US magazine Neuron.
They are trying to produce the images from the brain activity.They are in the initial stages at which they can only produce some simple images from the brain.
When people look at an object, the eye's retina recognises an image that is converted into electrical signals which go into the brain's visual cortex. Well it can be another giant step in the technology if this research gets succeeded.
