Abstract
Cross-modal interactions between somatosensory (S) and visual (V) stimuli have been demonstrated using behavioral, electrophysiological and neuroimaging techniques. The present study used recordings of event-related potentials (ERPs) to investigate the neural basis of S/V interactions as a function of the spatial congruity of the S and V stimuli. We presented random streams of S, V, and bimodal SV stimuli to human subjects from two distinct spatial locations. The subjects’ task was to detect slightly more intense targets in either of the two modalities at either location. The S stimuli were generated by an electro-mechanical device located under the subject’s finger tips, and the V stimuli employed light-emitting diodes (LEDs) mounted in very close proximity to the stimulated areas of both hands. The present study analyzed the spatio-temporal ERP signatures of cross-modal S/V interactions as a function of whether the bimodal SV stimuli occurred at the same versus different locations.
