Recognition Thresholds and Accuracy for Differing Body Regions as a Function of Number of Electrodes and Their Spacing

Abstract

Recognition thresholds and maximum accuracy levels were established on 12 Ss as a function of number of electrodes (2, 3, 4, and 5) and inter-electrode distance for various body regions (chest, abdomen, and back). There was little systematic difference among body regions with respect to the threshold and accuracy data; however, the number of electrodes proved to be significant. The abdomen appeared to be a slightly more favorable electrode site with a 5-electrode array.
