Spontaneous emergence of leadership patterns drives synchronization in complex human networks

Abstract Synchronization of human networks is fundamental in many aspects of human endeavour. Recently, much research effort has been spent on analyzing how motor coordination emerges in human groups (from rocking chairs to violin players) and how it is affected by coupling structure and strength.
