Sony researcher develops method for direct brain stimulation
by Mike Adams, the Health Ranger, NaturalNews Editor
Thomas Dawson, a research scientist working for Sony, has been granted a patent for a technique that uses ultrasonic pulses aimed at tiny individual areas of the brain to create sensory experiences, including tastes, smells, sights and sounds. Sony says that Dawson has not yet conducted experiments with the technological innovation. The new technique could be used by Sony, the makers of the Playstation video game console, to create more realistic and immersive games, and could also be used by medical researchers to help the disabled by creating devices to let the blind see or the deaf to hear.
If you think video games are engrossing now, just wait: 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 U.S. patent, granted to Sony researcher Thomas Dawson, describes a technique for aiming ultrasonic pulses at specific areas of the brain to induce "sensory experiences" such as smells, sounds and images.
"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."
According to New Scientist magazine, the first to report on the patent, Sony's technique could be an improvement over an existing non-surgical method known as transcranial magnetic stimulation.
This activates nerves using rapidly changing magnetic fields, but cannot be focused on small groups of brain cells.
Niels Birbaumer, a neuroscientist at the University of Tuebingen in Germany, told New Scientist he had looked at the Sony patent and "found it plausible."
Birbaumer himself has developed a device that enables disabled people to communicate by reading their brain waves.
A Sony Electronics spokeswoman told the magazine that no experiments had been conducted, and that the patent "was based on an inspiration that this may someday be the direction that technology will take us."
