Figure 7From: Impacts of selected stimulation patterns on the perception threshold in electrocutaneous stimulationRelationship between the normalized PTs and the interleaved time between two channels. A. E1&E2. B. E1&E4. C. E3&E5. A sigmoid relationship was estimated between the PT and the interleaved time t: log (PT) = c + d/t. The highlighted electrodes in the inset schematic indicate the location of active electrodes corresponding to the figure.Back to article page
