Tiny Wireless Device Casts Light On Brain's Inner Workings


A team of researchers, including UArizona Biomedical Engineering professor and BIO5 member Dr. Philipp Gutruf, have developed a device that could provide unique insight into the mechanisms of pain, depression, addiction and certain diseases. The ultra-small, wireless, battery-free device uses light to record individual neurons so neuroscientists can see how the brain is working.
