New nano-implant could one day help restore sight

A team of engineers at the University of California San Diego and La Jolla-based startup Nanovision Biosciences Inc. have developed the nanotechnology and wireless electronics for a new type of retinal prosthesis that brings ...

Brain-machine interfaces: Bidirectional communication at last

A prosthetic limb controlled by brain activity can partially recover the lost motor function. Neuroscientists at UNIGE asked whether it was possible to transmit the missing sensation back to the brain by stimulating neural ...

Artificial retinas—promising leads towards clearer vision

A major therapeutic challenge, the retinal prostheses that have been under development during the past ten years can enable some blind subjects to perceive light signals, but the image thus restored is still far from being ...

Opposites don't attract when learning how to use a prosthesis

New research suggests that upper limb amputees, who typically struggle to learn how to use a new prosthesis, would be more successful if fellow amputees taught them. Most usually learn by watching a non-amputee demonstrate ...
