Until now, dreams are the one which makes people to wonder. In the past we would say whether our dreams will come true or not. Some people would have a dream which they want to see again. Some may have a haunted dream. So dreams are of many kinds. But now dream is no longer a imaginary one. It can be visualized. Scientist’s team in the U.S lead by Professor Jack Gallant of University of California said that they have a computer to decode the brain activity signals from a scanner and match the photos of what a person has seen. This is a mind- reading technique opted by the scientist’s.
The result of this activity is they say that soon it will become to construct a picture of a person’s visual experience from the measurements of the brain activity alone. They also feel that the information they obtain from the brain activity signals might potentially be sufficient. The signals from the brain are measured using (fMRI) functional Magnetic Resonance Imaging. The further enhancement of this is it may become possible to re-construct the visual contents of one’s dream. The main intention of this research is to understand the mental state of a person who is in coma.
Conversely, it inevitably raises a fear that such technology could be used to grill a person for “thought crimes”.
