Cortical magnification factor measured for phosphenes evoked by neighboring electrodes within multi-point sequence. Analysis was restricted to electrodes in V1. A. CMF across all multi-point sequence trials for BS1. Each point is CMF calculated for a pair of phosphenes on a single trial. Black lines indicate expected pattern of CMF across eccentricity based on the visual mapping function described in methods. B. CMF across all multi-point sequence trials for BS2.
