Figure 12:

Correlations of response patterns between 20-times ratio asymmetric anodic-first pulse with different delivered charges and control symmetric cathodic-first pulses with fixed delivered charge (60 μA) that generally leads to focal response ((A): Result of WT; (B): Results of RD). The averaged correlation plot across multiple regions identifies the required amount of charge for 20-times ratio asymmetric anodic-first pulse to produce similar response as control symmetric cathodic-first pulse (23 regions of 6 WT animals and 15 regions of 5 RD animals).
