The study of hemispheric asymmetry in olfaction in human subjects has given rise to many publications, but the findings have often been contradictory. This study used bilateral electrodermal activity recordings with unilateral stimulation as a measure of functional hemispheric asymmetry. A specific odorant (lavender) was used by monorhinic (single nostril) stimulation on 30 dextral subjects (20 females and 10 males). Intraindividually, the results showed no difference between the two nostrils, but all subjects exhibited a constant direction of electrodermal asymmetry: 20 subjects systematically showed a greater response amplitude for the right hand and 10 subjects systematically showed a greater response amplitude for the left hand, whatever hemisphere stimulated.
对人类嗅觉中半球不对称性的研究催生了许多出版物，但研究结果往往相互矛盾。本研究采用单侧刺激下的双侧皮肤电活动记录作为功能性半球不对称性的一种测量方法。对30名右利手受试者（20名女性和10名男性）通过单鼻孔（单侧鼻孔）刺激使用一种特定的气味剂（薰衣草）。在个体内部，结果显示两个鼻孔之间没有差异，但所有受试者都表现出皮肤电不对称性的恒定方向：无论刺激哪个半球，20名受试者系统性地表现出右手的反应幅度更大，10名受试者系统性地表现出左手的反应幅度更大。
