| Research Abstract |
Using intrinsic signal optical imaging, it has been confirmed that in the visual cortex of kittens exposed to a single orientation, the representation of the exposed orientation occupied a marge cortical territory, and that there is a sensitive period during which this alteration of orientation maps occurs. In this study, using a self-organization model based on the NMDAR mechanism, we performed simulations of orientation map alteration under single-orientation exposure for a fixed period following normal visual experience. The simulations demonstrated to well reproduced the experimentally observed features of map alteration by single-orientation exposure.
