| الوصف: | Trajectories from a pair of interacting zebrafish are used to test for the existence of anticipatory dynamics in natural systems. Anticipatory dynamics (AD) is unusual in that causal events are not necessarily ordered by their temporal order. However, their causal order can still be established if the direction of information flow (DIF) is known. In order to obtain DIF between trajectories of the two fish, we have made use of the difference of the transfer entropy between the trajectories with a history length established by experiments with known DIF. Our experimental results indicate that AD can be observed much more often in fish pairs of different genders. The use of DIF to determine causal order is further verified by the simulation of two chaotic Lorenz oscillators with anticipatory coupling; mimicking the interaction between the fish. Our simulation results further suggest that the two fish are interacting with their own internal dynamics, not by adaptation. |
