| Research Abstract |
We investigated how the system responds to an environmental change in space and time for the following cases: self-generation of traveling pulses at the defect points in the media, synchronization and de-synchronization of EEG by the stimulus of TMS, and a flexible switching of attractors in response to the environmental change. As for the pulse-generators, it was found that double-homoclinic-loop of butterfly type plays an organizing center from dynamical system point of view. An oscillator network model of FHN type with multiple internal states was presented to explain the above dynamical behaviors of EEG. Also it was shown that such a network model has a spontaneous loop-finding ability and robust against the destruction of such structure.
