The goal is to bring the technology to the point where they will be able to extract information that people see exactly at a certain time.

If some neuroscientists are right, with good technology science could draw pictures, and one day and thought, directly from the brain of people. Apparently scientists can predict the last image that had been seen only by analyzing activity in the brain. The technique is called neural decoding.

To do this, scientists must first scan the brains of subjects while he watches thousands of pictures. A computer then analyzes how the brain responds to each of them. Over time, the computer creates its own way of decoding that is later used to identify and reconstruction of the respondents saw without analyzing images.

Neuroscientist Jack Gallant for 10 years leading laboratory for neuroscience and psychology. Gallant is one of the rare neuroscientists in the world that weighs search formula to read thoughts by analyzing patterns in the brain using magnetic resonance imaging and algorithms. His current method requires several hours to analyze the content of the subject's brain, but his goal is to bring the technology to the point where they will be able to extract information that people can see exactly at a certain point. If he succeeds in this, it will affect many more.

The mechanisms for reading thoughts could help doctors understand the inner world of people who have hallucinations, cognitive disorders, PTSP and the like. Also, the court could these mechanisms be useful. Through them, the judges could take a peek into the mind of suspects and extract the necessary information by reading their vision. Such mechanisms could be used to confirm and someone false defense by insanity or someone defends solely because he fears for his life. Far from the paranormal, Gallant believes that the mind-reading just a matter of the estate of adequate tools.

Owning quality and adequate measurement of brain activity and good computer models of the brain, would allow decoding of the visual content of mental processes such as dreams, memory and imagination. However, on the other hand, this technology raises serious ethical problems which critics believe that one day could become a reality. For example, it is possible that this technology is used for reading private thoughts...
