This study investigated olfactory lateralization and identification in right hemisphere lesion and control patients. Significant group differences were found for olfactory and trigeminal lateralization and identification on unilateral and double simultaneous stimulation. In the control group, significantly greater than chance accuracy was found for lateralization and identification, whereas in the lesion group, significantly greater than chance accuracy was found for identification but not for lateralization. Olfactory detection thresholds were found not to be significantly different between the groups.
本研究调查了右半球损伤患者和对照患者的嗅觉偏侧化及识别情况。在单侧和双侧同时刺激下，嗅觉和三叉神经偏侧化及识别方面发现了显著的组间差异。在对照组中，偏侧化和识别的准确率显著高于随机水平；而在损伤组中，识别的准确率显著高于随机水平，但偏侧化方面并非如此。发现两组之间的嗅觉检测阈值无显著差异。
