Brain-computer interfaces have a structural impact on brain substance.

Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? Scientists have now identified the neural circuit in the brain of fruit flies which makes them perform at their best when searching for food.

It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. Even better, the devices work through a full head of hair. The researchers now report on the flexible electrodes, which could someday be used in brain-computer interfaces to drive cars or move artificial limbs.

Scientists have successfully tested new neuroprosthetic technology that combines robotic control with users' voluntary control, opening avenues in the new interdisciplinary field of shared control for neuroprosthetic technologies.

Scientists are blurring the distinction between brain and machine, designing nanoelectronics that look, move, and feel like real neurons. Camouflaged in the brain, this technology could offer a better way to treat Alzheimer's disease or post-traumatic stress disorder, control prosthetics, or even enhance cognitive abilities.
