Fig. 7

Responses to stimulation by 100 μm diameter disk electrodes at different ERDs. a-d Qualitative results under the stimulation of 1.0 ×, 1.1 × and 1.2 × TC. Top: the electric field distribution in the retina; Bottom: the activating results of RGCs. Red points meant activated RGCs, while blue ones meant non-activated RGCs. a ERD = 20 μm. b ERD = 40 μm. c ERD = 60 μm. d ERD = 80 μm. e Correlations among TC, TCD, and the ERD (f) Correlation between activated RGC area and stimulating current at different ERDs
