| Lecturer(1) | "The contingent brain" |
| Speaker | Mr. Kenichiro Mogi (Sony Computer Science Laboratories, Inc.) |
| Abstract | In this talk, I will discuss how the brain processes contingency encountered in the interaction with the environment. Recent developments in neuroeconomics and the dynamics in brain's reward system have brought about a new understanding of how the brain overcomes contingency. I will review recent work as well as report some new findings. |
| Lecturer(2) | "Local mechanism for global adaptation in binocular rivalry" |
| Speaker | Mr. Fumihiko Taya (Sony Computer Science Laboratories, Inc.) |
| Abstract | Binocular rivalry, where each image competes to emerge in the visual field during the presentation of dissimilar images to the right and the left eye, is widely known. First, we suggest the spatio-temporal method to study the spatio-temporal structure of the wide visual field. By using this method, we have studied how the visual system assigned the visual field while we presented salient features, e.g. the moving objects. Based on the result, we will discuss the possibility that the small world network architecture, where the local and the global interactions among neurons at an early stage of the visual processing, plays an important role in the adaptation of the visual system to the dynamically changing external environment. |
