Modulation of intracellular rhythm and behavior of physarum plasmodium under the condition of mutual entrainment

摘要

Organism is considered to have dynamics based on some interactions and shows complicated behavior. We suggested the experiment in which the interaction between artificial oscillator to cause entrainment and metabolic oscillation in organism which is physarum plasmodium in this study. Because a coupled oscillators model for physarum shows mutual entrainment among each oscillators and formed phase pattern which is shown in tactics response of physarum. The results shows that mutual entrainment could be observed, intracellular rhythm was modulated with artificial oscillation and plasmodium migrated according to the orientation of intracellular rhythm modulation and these results are not contradictory with past investigation of tactic response.
