Outline of Final Research Achievements

Orientation selectivity has been believed to first emerge in the primary visual cortex. Our research revealed that 1) retinal ganglion cells and neurons in the lateral geniculate nucleus, the pre-stage of primary visual cortex exhibited significant orientation selectivity, and that 2) there were excitatory connections between neurons with similar preferred orientations in the early visual pathway. These results suggest that orientation selectivity of visual neurons is originated in the retinal ganglion cells.
