Research Areas

We focus on brain rhythms and their synchronization as a neuronal principle for social intelligence through their emergent adoptive properties. Our research aim is to clarify the neural network model for social communication based on brain rhythms. These studies are devoted to robot design in a social system with human-robot communication.

Research Subject

  1. Brain Imaging studies on the human communication
  2. Computational studies on social intelligence based on rhythm neural networks
  3. Working memory, its neural dynamics and cognitive control
