Comparing cutaneous perception induced by electrical stimulation using rectangular and round shaped electrodes

► We have tested the cutaneous perception characteristics of tDCS and tRNS in the intensity range of 200-2000 μA using a circle-shaped and a rectangle-shaped sponge electrode configuration. ► No substantial differences between the two configurations have been observed. ► Round sponge electrodes do not have better blinding properties compared to the rectangular electrode configuration.
