摘要

To investigate the cortical mechanisms underlying the determination of apparent tilt, including the tilt illusion, we developed and examined a V1 network model consisting of cortical neurons and phase-coupled oscillators for neural grouping. Grouping local orientations based on V1 colinear connections, the model showed quantitative agreement with psychophysically measured apparent tilt. Computational investigations suggest that even-phase receptive fields are crucial but not exclusive for the apparent orientation of a bar. Our results further suggest importance of the feedback of grouping information from complex cells, which are synchronized through colinear connections, to simple cells with specific phases.
