Figure 6From: Impacts of selected stimulation patterns on the perception threshold in electrocutaneous stimulationRelationship between the normalized PT and the number of pulses. A. E1&E2. B. E1&E4. C. E3&E5. An inverse relationship between the PT and the pulse number n: PT = a + b/n was found in all the three electrode combinations. The highlighted electrodes in the inset schematic indicate the location of stimulated electrodes corresponding to the figure.Back to article page
