Show Me What's on Your Mind
Mind reading has been brought to a more scientific level.

Using a computer program, correlations between the configuration of shapes, colours and movements in videos, and patterns of activity in the brain's visual cortex (monitored using a functional magnetic resonance imaging machine) were determined. The program was also trained to identify areas of the brain that is triggered by certain video clips should people be watching them. The result: a nearly perfect reproduction of images as they are being played before test subjects.
The technology was developed by Jack Gallant and Shinji Nishimoto, two neurologists from the University of California, Berkeley.
