"Sun and her colleagues leverage a method developed at the lab of Harvard Professor of Psychology and Neuroscience Randy Buckner to identify and target these networks in individual subjects using functional magnetic resonance imaging (fMRI), which measures brain activity by detecting changes in blood oxygen levels. 'At Buckner lab, we recruit human subjects and put them in an MRI scanner,” Sun explains. “We ask them to do various tasks like remembering the past or imagining the future, and we scan the subjects very intensively over a course of several months using fMRI imaging to get a proxy of brain activity, measure, and characterize their neural networks.'"
