Uncharted territory: Expert discusses technology to map brain activity
Medical Xpress November 11, 2024
To understand how different regions of the brain work together, researchers use a method called resting-state functional magnetic resonance imaging (rsfMRI). The method measures brain activity by observing changes in blood flow to different parts of the brain; however, rsfMRI does not explain how these blood flow changes to different brain regions relate to what is happening with the brain’s neurons—cells that send and receive messages in the form of electronic signals.
A team of researchers led by Nanyin Zhang, the Dorothy Foehr Huck and J. Lloyd Huck Chair in Brain Imaging and professor of biomedical engineering at Penn State, set out to answer this question. They recently published their findings, made in mice, in the journal eLife.
