For centuries, scientists have been fascinated by the remarkable coordinated movements of flocking birds, swarming insects and schooling fish. Researchers have studied these natural phenomena to understand the rules of interactions between individuals that can produce complex group-level behavior. A collaboration of physicists and neurobiologists at the University of California San Diego has been studying schools of micro glassfish (Danionella cerebrum) to understand how the interactive mental processes of individual fish produce group-level decisions. ...read more read less
