Brain control devices
-> As much as it may seem the stuff of science fiction, Hitachi researchers have developed a device which measures changes in brain blood flow, and by using biofeedback, allows the user to control external devices. Currently the technology is still quite basic, and rather than think of moving the object, users instead do sums or sing a song. The device detects the blood flow changes as the frontal cortex and translates them into a control signal for whatever device the user wishes to run. In the Hitachi experiment, a TV was turned on and off and channels changed. ***Ed: With more refinement, this device would be a blessing to physically disabled people such as those having suffered a severe stroke.**
