An EU team studied the cognitive role of dynamic linkages among brain regions. Using new analytical methods offering treatment applications, findings revealed single connection-events, and showed that activity generally fills cortex grey-matter.
Human brains are ceaselessly active; the activity includes very brief connections among regions of the brain having specialised function, and supports cognitive function. Yet imaging and studying such transient processes is difficult, particularly given paradigms assuming permanence of functional neural networks.
