| Abstract(in English) | Neurophysiological experiments have revealed that post-synaptic effect conveyed by long-range horizontal connections (LHC) in V1 can be excitatory or inhibitory, and the effect highly depends on the activity of pre-synaptic neurons (non-linearity of horizontal connections). Almost all of computational studies about LHC have been based on contour integration. However, contour integration cannot explain the non-linearity of LHC. In this study, the author proposes image-reconstruction as the computational role of LHC in V1 instead of contour integration. The spatial distribution of LHC and the non-linear property are theoretically derived from the dynamics for image-reconstruction. It is shown that the theoretically obtained distribution of LHC and the non-linear property are qualitatively consistent with neurophysiological findings. Numerical simulations show the effectiveness of the proposed model from engineering points of view. |
