Outline of Final Research Achievements

First, we modeled infant's General movements by a combination of a complex nonlinear oscillator network and musculoskeletal body model. We observed that the model generates diverse behaviors depending on the condition of the networks and the interaction between the network and the body. The experiments indicated that the structure with strong local connectivities and interactions ruled by either side of the dynamics induces poor repertoire of the movements. We discussed about structural origin of the developmental change of the infants's movements based on the experimental results.
Second, we conducted experiments with spiking neural network connected by complex network structure. We observed that the complexity of the activity of the network decrease when the network has relatively strong local connectivities. The result corresponds to the brain wave analysis for Autistic Spectrum Disorder or schizophrenia and shows the developmental process based on structural starting point.
