Abstract :
Coupled oscillator systems with oscillating cells of plasmodium of the true slime mold were constructed with a cell pattering method using microfabrication technique. Parameters in this system such as coupling strength can be systematically controlled like in computer simulations. We constructed three-oscillator systems in rings and observed spontaneous switching among typical spatio-temporal patterns even when coupling strength was fixed.
