| Outline of Final Research Achievements |
This work investigated in primary dissociated cultures how neural circuits produce diversity of activity repertoire and how the static neural circuits produce stable, dynamic spatiotemporal patterns. In particular, considering a framework of reservoir computation, we characterized the neuronal circuits as a reservoir. We demonstrated that sequential propagation of neuronal sub-populations during synchronized activity underlies stability of neural representation. We also found a spontaneous, state-dependent property of neuronal activities, which is likely to play an important role to produce diversity of activity repertoire.
