Relative nostril efficiency (nasal cycle) is related to hemispheric EEG differences and performance on cognitive tasks. We investigated how unilateral forced nostril breathing influences spatial and verbal performance. Right-handed males and females performed both tasks under either left-nostril, right-nostril, or free-breathing conditions. Unilateral breathing affects performance differently in males and females. It influences male performance ipsilaterally on both tasks: Their spatial performance is better during right-nostril breathing, and their verbal performance is better during left-nostril breathing. Unilateral breathing influences female performance contralaterally, but only on the spatial task: Their spatial performance is better during left-nostril breathing. These differences within and between sexes may exist because unilateral nostril breathing differentially activates the two hemispheres and thereby facilitates performance, or because attempts of the brain to control the nasal cycle unilaterally interfere with performance.
相对鼻孔效率（鼻周期）与半球脑电图差异及认知任务表现有关。我们研究了单侧强制鼻孔呼吸如何影响空间和语言表现。右利手男性和女性在左鼻孔、右鼻孔或自由呼吸条件下完成这两项任务。单侧呼吸对男性和女性表现的影响不同。它对男性在两项任务中的表现均产生同侧影响：他们在右鼻孔呼吸时空间表现更好，在左鼻孔呼吸时语言表现更好。单侧呼吸对女性表现产生对侧影响，但仅在空间任务中如此：她们在左鼻孔呼吸时空间表现更好。性别内部和之间的这些差异可能存在，是因为单侧鼻孔呼吸以不同方式激活两个半球，从而促进表现，或者是因为大脑单侧控制鼻周期的尝试干扰了表现。
