Abstract

We investigated the effects of forehead temperature stimulation on total respiratory resistance in healthy individuals. In two experiments involving a total of 38 participants we studied the time course and stability of the response at moderate temperature (20-23 degreesC). Small plastic bags filled with water were positioned on the forehead for a duration of 60 s. Oscillatory resistance (R-os), heart period (HP), respiratory sinus arrhythmia (RSA), and ventilatory parameters were measured continuously. Experiment 1 showed similar phasic increases in R-os during the first 20 s of stimulation with moderate (20-23 degreesC) as compared to cold (8-11 degreesC) temperature. Phasic increases by moderate temperature were replicated in Experiment2 over five successive stimulation trials. Within-session stability of individual differences in response was only modest. Ventilatory adjustments did not facilitate the phasic R-os increases. As increases were mainly due tothe inspiratory component of R-os. a substantial contribution of upper airway artifacts was less likely. Increases in HP were the most pronounced responses to all stimulation conditions. while RSA did not increase significantly. (C) 2000 Elsevier Science B.V. All rights reserved.
