The effect of human skin temperature on electrocutaneous sensitivity was examined using brief capacitive discharges. Stimuli were designed to ensure that sensory effects would be independent of skin resistance and would reflect underlying neural excitability as closely as possible. Skin temperature was manipulated by immersing the forearm in circulating hot or cold air. Detection thresholds on the arm and fingertip were raised by cooling, but were not altered by heating. Temperature-related sensitivity shifts were described by the same multiplicative factors for both threshold and suprathreshold levels. The temperature coefficient (Q10) for cutaneous sensitivity under these conditions was approximately 1.3.
使用短暂电容放电来研究人体皮肤温度对皮肤电敏感性的影响。设计刺激以确保感觉效应与皮肤电阻无关,并尽可能紧密地反映潜在的神经兴奋性。通过将前臂浸入循环的热空气或冷空气中来控制皮肤温度。冷却会提高手臂和指尖的检测阈值,但加热不会改变阈值。阈值和阈上水平的温度相关敏感性变化由相同的倍增因子描述。在这些条件下,皮肤敏感性的温度系数(Q10)约为1.3。
