Sony patents tv for the brain.

No matter how crisp your display is or how many speakers you have in your home theater, you can receive their information through your eyes and ears only. How about "playback systems" that bypass physical sight and hearing? Consider two recent Sony patents (#6,536,440 and #6,729,337) titled "Method and System for Generating Sensory Data onto the Human Neural Cortex" and a patent application (#20040267118) titled "Scanning Method for Applying Ultrasonic Acoustic Data to the Human Neural Cortex." They describe a noninvasive way to create sensory perceptions across the neural cortex. For example, "imagery captured from a video camera is converted into neural timing difference data" and scanned across the brain as "pulsed ultrasonic signals that modify the firing rate of the neural tissue." In this manner, "sensory experiences arise from the differences in neural firing times."
