Three experiments were performed to investigate the effect of strong shock on absolute electrocutaneous thresholds. Experiment 1 confirms the existence of a reliable elevation of absolute threshold after strong shock. Experiment 2 shows the effect to be highly localized to the site of the strongly shocked electrode. It also shows that threshold elevation does not follow the same time course as do local vascular and impedance changes. Experiment 3 used skin treatment to alter the local vascular and impedance levels and demonstrated that threshold elevation occurs after strong shock even after these measures have been stabilized. These data indicate that the threshold increase due to electric shock is probably analogous to auditory fatigue but does not rule out the possible involvement of more central control factors.
