A boost in the speed of brain scans is unveiling new insights into how brain regions work with each other in cooperative groups called networks.

Researchers at Washington University School of Medicine in St. Louis and the Institute of Technology and Advanced Biomedical Imaging at the University of Chieti in Italy are turning to faster technology called magnetoencephalography (MEG) to sample neural activity every 50 milliseconds.

In doing so, they’ve been afforded novel insights into the inner-workings of neural networks in resting and active brains. As the researchers report in the journal Neuron, these new insights could help us better understand how brain networks function and, in turn, better diagnose and treat brain injuries.
