Sony Prepares to Beam Into Your Brain

"PlayStation maker Sony has been granted a patent for beaming sensory information directly into the brain. The technique could one day be used to create videogames in which you can smell, taste, and touch, or to help people who are blind or deaf.

"The pulsed ultrasonic signal alters the neural timing in the cortex,' the patent states. 'No invasive surgery is needed to assist a person, such as a blind person, to view live and/or recorded images or hear sounds.'"
