| Abstract: | Temporal order thresholds were measured for brief electrical stimuli presented to the forehead and to the abdomen. Temporal acuity is better (thresholds smaller) on the forehead, sensitivity increasing somewhat (thresholds decreasing) as the physical separation between the electrodes increases. Even in that subject, of four, who had the lowest thresholds, however, the value rarely fell below 100 msec. Temporal order thresholds also depend on the orientation, being far smaller when the electrodes are separated horizontally than when separated vertically on both body sites. |
