Researchers Take Step Toward Next-Generation Brain-Computer Interface System

Brown University, August 12, 2021

A team of scientists from Brown University, Baylor University, the University of California, San Diego, and wireless technology company Qualcomm has moved a step toward a future brain-computer interface system that uses a network of ultra-small sensors to record and stimulate brain activity. These silicon "neurograins" independently capture and transmit neural signals wirelessly to a central hub for coordination and processing; the hub is a thumbprint-sized patch attached to the scalp, which also wirelessly powers the tiny chips. The team used 48 neurograins to record signals in a rodent characteristic of spontaneous brain activity, and to stimulate activity through tiny electrical pulses. Brown's Arto Nurmikko said, "Our hope is that we can ultimately develop a system that provides new scientific insights into the brain and new therapies that can help people affected by devastating injuries."
