  "account": "For centuries, scientists have marveled at the synchronized movements of groups of animals like birds, insects and fish. Researchers have sought to understand the interactions between individuals that result in the complex behavior seen in these groups. Now, a team of physicists and neurobiologists at the University of California San Diego are studying schools of micro glassfish (Danionella cerebrum) to discover how individual fish's perceptions of their neighbors' movements contribute to the group's overall behavior. Led by Palka Puri, a recent UC San Diego physics Ph.D. graduate, the study reveals that micro glassfish synchronize by rapidly copying the direction of a single neighboring fish. This pairwise interaction, rather than averaging the movements of multiple neighbors, leads to dynamic group behavior that differs from classical models of collective motion. The researchers tested their model by simulating virtual fish in a virtual reality environment; the real glassfish responded to these virtual neighbors in ways consistent with the model's predictions. They also found that the timing of these copying interactions is crucial, with mature glassfish executing the behavior with fast reaction times, offering insight into the rapid social exchanges that characterize school life. This discovery could lead to a deeper understanding of how individual brain processes contribute to collective movement, with the potential to reveal how the tiny brains of these fish coordinate their actions with neighbors.",
  "summary": "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…",
