Researchers at the Fralin Biomedical Research Institute at Virginia Tech Carilion School of Medicine (VTCSM) received a $2.4 million National Institutes of Health grant to use optically pumped magnetometry to explore neural activity during face-to-face human interactions. The researchers will optically measure the brain’s magnetic signals in two research volunteers simultaneously as the volunteers interact, capturing the nuances of the brain’s signaling in real time.
Brain cells generate electrical currents that emit tiny magnetic fields. Optically pumped magnetometers use quantum sensor chips to measure the strength and originating location of these fields, and they are sensitive enough to detect magnetic fields on the…READ MORE
