Abstract(in English)	We have investigated synchronization in coupled systems with a star-like configuration (hub structure). In a previous study, we found that the stability of cluster synchronized states can be controlled by a firing frequency of a central node in coupled Morris-Lecar neurons. In this study, two systems: a neuron model and an electric circuit are considered to check universality of this phenomenon. As a result we also observe it for both systems. When there is coexistence of some synchronized states for two mutually coupled neurons and a hub network composed of such a coupling unit is constructed, we can control the appearance of synchronized states by changing a oscillation frequency of a central node.
