Hiroaki Wagatsuma (Kyushu Institute of Technology, RIKEN) will be at Loria until June 28th. He will give a talk entitled “Brain-inspired robotics: Neural Dynamics for the Body Coordination and Interactions with the Environment” on Wednesday 19 June, 10:00am in room C005.

Abstract
The first issue that he tackled was the elucidation of the mechanism how different time scales of a behavior and synapses are associated according to the rhythm and he currently extended it to the question of how a rhythm (a specific type of the limit cycle in the system) transits to the other, dynamically and sophisticatedly, i.e. a structural design of the trajectory or self-organization of multiple rhythms for a complex function. For example, a synchronous motion spontaneously appears in communication between persons faced each other and their motions differentiate as time advances because they need to express the own expressions each other. A typical example is an interactive game with motions. For judging or proceeding from a stage to the next stage, the counterpart with a different motion have to synchronize at some moment, which is a result to compete and determine which is winner, or looser. A possible hypothesis is that such a quasi-equilibrium state is emerged from the coupling between the behavioral coordination and neuronal dynamics including the coordination and a conflict in the internal decision-making process. He discussed on the issue in the talk.
