Temporal resolution of successive brief stimuli for the tongue and hand

  • Linda Petrosino

The temporal resolving power of the tactile sensory system was examined by obtaining fusion thresholds for a two-pulse vibratory stimulus. Fusion thresholds were obtained from the tongue and thenar eminence of the hand for 24 adult subjects. The means of the fusion thresholds for the tongue (24.63 msec) for the thenar eminence (24.73 msec) were found to be statistically similar. The similarity in fusion thresholds for the two test sites suggests that for this suprathreshold task the tactile modality responds as a whole, regardless of body location. Results are discussed with respect to cutaneous fusion values already reported in the literature.
