Summary:
In a general sense, binding is dynamical coupling between distant regions in the brain. Although its detailed mechanism has not been well understood, it is suggested that binding can be perceived from the dynamical system’s viewpoint. In order to examine the binding mechanism from this standpoint, here we propose a meso-scopic model that describes each region’s dynamics abstractly. The model is characterized by the following two points: (1) Spatio-temporal patterns of regional activities are symbolically represented by simple limit-cycle orbits, and (2) binding is realized as a form of mutual excitation among these orbits. Preliminary numerical simulations show that various patterns of binding can be generated. Furthermore, attractor switching is also observed according to conditions. This study supports the idea that the dynamical system’s point of view is effective to understand binding mechanism as well as other brain functions.
