Abstract
The part-whole relations found in seriatim warm-mapping are virtually identical with those earlier reported for cold. Aside from a minor effect of size as such, whole scores are expressed as a square-root function of part scores. Seriatim maps with a 1 mm diam. stimulator show no isolated warm spots. Neither the traditional warm spot theory, nor the thermal-conduction modification of it provides an adequate explanation of the experimental facts. Warm sensitivity, like cold sensitivity, is best explained in terms of a concentration theory; i.e., that sensitivity is detd. by the conc. of minute receptors.
