TRANSMITTING SENSORY DATA INTO THE HUMAN BRAIN
While brain implants are becoming increasingly sophisticated, the only non-invasive ways of manipulating the brain remain crude. A technique known as transcranial magnetic stimulation can activate nerves by using rapidly changing magnetic fields to induce currents in brain tissue. However, magnetic fields cannot be finely focused on small groups of brain cells, whereas ultrasound could be.
The entertainment giant Sony has been granted a patent on a device for transmitting sensory data directly into the human brain. The device fires pulses of ultrasound at the head to modify firing patterns in targeted parts of the brain, creating "sensory experiences" ranging from moving images to tastes and sounds.
Sony first submitted the patent application for the ultrasound method in 2000, which was granted in March 2003. Since then Sony has filed a series of continuations, most recently in December 2004 (US 2004/267118).
