Abstract : Galvanic skin resistance, arteria radialis pulse and blood pressure, respiration, and stomach motility were recorded electromechanically in man after olfactory stimulation. In most cases, skin resistance decreases rapidly and returns gradually to its original value frequently with temporary decrements in between. Arteria radialis pressure often shows a decrease, followed by a wavy pattern of alternate increments and decrements, before returning to its original value. Pulse frequency and amplitude are hardly affectd. Respiration becomes often deeper during stimulation with pleasant odors, while its amplitude decreases with unpleasant odors; however, a partial increase of the respiratory amplitude with unpleasant odors has also been observed in some cases. Stomach motility increases in almost all cases, in the form of increased amplitude of contraction, persistent contraction, or increased frequency of contraction. It is concluded that the largely autonomous cycles of the parameters investigated are affected by olfactory stimuli, the effects depending on the particular conditions prevailing in the autonomic nervous system at the time of stimulation.
