TI  - Recovery functions of somatosensory vertex potentials in man: interaction of 
      evoked responses from right and left fingers.
PG  - 531-5
AB  - Somatosensory vertex potentials (SVPs) were examined in 12 healthy subjects in 
      response to painful electrical stimulation of the finger. SVPs consisted of N1, 
      P1, and N2. The average latencies of the 3 peaks were 150, 225, and 350 msec, 
      respectively. The latency and amplitude of each potential were reproducible for 
      each subject. Recovery functions of the SVPs were analyzed in 10 subjects. A pair 
      of stimuli were delivered to the right or left finger with interstimulus 
      intervals (ISIs) of 50, 100, 150, 200, 350, 500 and 650 msec. SVPs partially 
      recovered with the shortest ISI (50 msec). Full recovery could not be obtained 
      even with the longest ISI (650 msec). Differences in recoveries within 650 msec 
      of ISI were not observed between right and left stimulations. To examine the 
      interaction between SVPs evoked by right and left finger stimulation, recovery 
      functions from prior contralateral finger stimulation were analyzed with the same 
      ISIs. SVP recoveries for right after left or left after right patterns of 
      stimulus delivery were nearly the same as those for ipsilateral ones. It is 
      suggested that SVPs are generated at nearly the same site in the sensory pathway 
      regardless of the side stimulated.
