THERMAL STIMULATION OF EXPERIMENTALLY VASOCONSTRICTED HUMMUH HUMAN SKIN,
Abstract
Measures of cutaneous thermal threshold were made at several adapting temperatures above and below normal surface temperature under control and conditions of superficial vasoconstriction by adrenaline chloride. Three practiced Ss reported thresholds which varied systematically from control thresholds although the resting temperature of the vasoconstricted area was maintained at the level of adjacent surface by artificial means. The thermal threshold varied with the degree of vasoconstriction and the adapting temperature. High negative correlations were found between the empirically determined warm thresholds in normal skin, and the degree of vasomobility was calculated from data which treated cutaneous microcirculation. The paucity of knowledge of histology of the innervation of the microcirculatory systems prevented a complete integration of data and theory. (Author)
