DARPA Funds Ambitious Brain-Machine Interface Program

The N3 program aims to develop wearable devices that let soldiers to communicate directly with machines.DARPA’s Next-Generation Nonsurgical Neurotechnology (N3) program has awarded funding to six groups attempting to build brain-machine interfaces that match the performance of implanted electrodes but with no surgery whatsoever. By simply popping on a helmet or headset, soldiers could conceivably command … Continue reading DARPA Funds Ambitious Brain-Machine Interface Program

KidneyX Prize Winners Rethink Dialysis

Artificial kidneys and a wearable that prevents blood clots were among the winning designsIn the 1960s, a pacemaker was the size of a microwave and a dialysis machine was the size of a refrigerator. Today, a pacemaker is the size of a vitamin and a dialysis machine is, well, the size of a refrigerator. They do … Continue reading KidneyX Prize Winners Rethink Dialysis

Brain Implant Can Say What You’re Thinking

A brain-computer interface that records signals in the motor cortex can synthesize speech from activity in a user’s brain Two years ago, a 64-year-old man paralyzed by a spinal cord injury set a record when he used a brain-computer interface (BCI) to type at a speed of eight words per minute. Today, in the journal Nature, … Continue reading Brain Implant Can Say What You’re Thinking

Gentle Brain Stimulation Improves Short-Term Memory

By synchronizing brainwaves, this therapy reversed age-related memory declineElectrical stimulation was once a last resort for the brain. Electroconvulsive therapy, for example, was developed to treat severe depression only after other therapies had failed. But times change and now we find ourselves in the era of gentle, non-invasive brain stimulation. Electrodes on the scalp have been … Continue reading Gentle Brain Stimulation Improves Short-Term Memory
