Now, Virginia Tech scientists can measure them using a new brain imaging technique called optically pumped magnetometry. Researchers at the Fralin Biomedical Research Institute at VTC have received a $2.4 million grant from the National Institute of Biomedical Imaging and Bioengineering, part of the National Institutes of Health, to measure the brain's subtle magnetic signals in two research volunteers simultaneously as they interact, capturing the rich complexity of the brain's signaling during face-to-face social interactions in real-time.
