Abstract

The purpose of this study was to investigate differences in brain activation by electrotactile stimulation of two fingers of the right hand with different frequencies using fMRI. Non-painful electrotactile stimuli were delivered. Significant activation produced by the stimulation were found in the SI, SII, subcentral gyrus, precentral gyrus, and insula. In all participants statistically significant activation was observed in the contralateral SI area and bilateral S? areas by the stimulation on the fingers but ipsilaterally dominant. The SI area representing the second finger generally located in the more lateral and inferior side than that of the third finger across all the subjects. But no difference in brain area was found for the stimulation of the fingers by different frequencies.
