Ultradian rhythms of alternating cerebral dominance have been demonstrated in humans and other mammals during waking and sleep. Human studies have used the methods of psychological testing and electroencephalography (EEG) as measurements to identify the phase of this natural endogenous rhythm. The periodicity of this rhythm approximates 1.5-3 hours in awake humans. This cerebral rhythm is tightly coupled to another ultradian rhythm known as the nasal cycle, which is regulated by the autonomic nervous system, and is exhibited by greater airflow in one nostril, later switching to the other side. This paper correlates uninostril airflow with varying ratios of verbal/spatial performance in 23 right-handed males. Relatively greater cognitive ability in one hemisphere corresponds to unilateral forced nostril breathing in the contralateral nostril. Cognitive performance ratios can be influenced by forcibly altering the breathing pattern.
在人类和其他哺乳动物的清醒及睡眠过程中，已证实存在交替性大脑优势的超日节律。人体研究使用心理测试和脑电图（EEG）方法作为测量手段，以确定这种自然内源性节律的阶段。在清醒的人类中，这种节律的周期约为1.5 - 3小时。这种大脑节律与另一种称为鼻周期的超日节律紧密相关，鼻周期由自主神经系统调节，表现为一个鼻孔气流较大，随后切换到另一侧。本文将23名右利手男性单侧鼻孔气流与不同比例的言语/空间表现进行了关联。一个半球相对更强的认知能力对应于对侧鼻孔的单侧强制鼻孔呼吸。通过强行改变呼吸模式，认知表现比例会受到影响。
