Chemicals selectively stimulating the olfactory nerve typically cannot be localized in a lateralization task. Purpose of this study was to investigate whether the ability of subjects to localize an olfactory stimulus delivered passively to 1 of the 2 nostrils would improve under training. Fifty-two young, normosmic women divided in 2 groups participated. One group performed olfactory lateralization training, whereas the other group performed cognitive tasks. Results showed that only subjects performing lateralization training significantly improved in their ability to lateralize olfactory stimuli compared with subjects who did not undergo such training.
化学物质选择性刺激嗅觉神经通常不能在侧化任务中定位。本研究的目的是调查在训练条件下，受试者是否能够提高将被动传递到两个鼻孔之一的嗅觉刺激定位的能力。52 名年轻的嗅觉正常的女性被分为两组。一组进行嗅觉侧化训练，另一组进行认知任务。结果表明，只有进行侧化训练的受试者在将嗅觉刺激定位的能力上有显著提高，而未接受这种训练的受试者则没有提高。
