Analysis of sympathetic activity induced by stimulation

Brain waves, sympathetic nerve activity, blood flow, perspiration and skin temperature induced by sensation stimulation were simultaneously measured in order to analyze mechanisms that cause skin temperature changes associated with sensations. The results suggested that stimulation of the sympathetic nerve system, including skin temperature, is induced when intense stressful stimulation is recognized, and also indicated that the reaction gradually declines even though it may at times recover to the level of an initial reaction. The results also suggested that skin sympathetic nerve activity (in the case of vasomotor) may decline as ambient temperature rises
