Structure of brain networks is not fixed (neurosciencenews.com)
Summary: Brain networks are spatially and functionally fluid, and not static, as previously believed. Source: Georgia State University 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 interaction and communication among neurons, known as “functionally connectivity,” gives rise to brain networks.
