Genetic 'Light Switches' Control Muscle Movement

Using light-sensitive proteins from a single-celled alga and a tiny LED "cuff" placed on a nerve, researchers have triggered the leg muscles of mice to contract in response to millisecond pulses of light. The paper's other senior author, Scott Delp, a ...

Awakening Paralyzed Limbs

A monkey with a paralyzed arm can still grasp a ball, thanks to a novel system designed to translate brain signals into complex muscle movements in real time. "It's much more natural, and if you can decode activity in enough muscles ...

Of cells and wires

They're just very little knives," says Robert Kirsch director of technology at the Functional Electrical Stimulation (FES) Center in Cleveland, a consortium that researches electrical shock in stimulating the nervous system. John Donoghue at Brown University, whose implanted electrodes let quadriplegic ...

Engineering the Brain: The Panel

Tomorrow at 3 P.M., I'm going to be speaking in a session on engineering the brain at MIT's Emerging Technologies Conference. Other participants will include Mark Humayun, who leads a team at USC that designs and builds retinal stimulators ...

A Prosthetic Arm That Acts Like a Real One

A new technique that capitalizes on remaining nerves allows amputees to intuitively control their prosthetic limb, providing them with a much better level of control than traditional prosthetics.. Todd Kuiken and colleagues at the Rehabilitation Institute of Chicago developed a new, more ...

A Brain Chip to Control Paralyzed Limbs

Scientists are now building a device that records brain signals and transmits them to paralyzed muscles, potentially returning muscle control to severely paralyzed patients. "Our ultimate goal is for a person to think and effortlessly move the arm ," says Robert Kirsch , associate ...
