Structure of Brain Networks is Not Fixed, Study Finds

The shape and connectivity of brain networks — discrete areas of the brain that work together to perform complex cognitive tasks — can change in fundamental and recurring ways over time, according to a study led by Georgia State University.
The researchers collected functional magnetic resonance imaging (fMRI) brain imaging data to create snapshots of network activity at a granular level over the course of several minutes, and observed rapid changes in the function, size and location of the networks.
