This preliminary study describes a noninvasive, inexpensive approach to the study of lateralization as related to mental activity. It supports the concept of a thermoregulatory role of blood in cerebral temperature control. Right and left angularis oculi vein temperatures were measured during periods of mental activity and mental rest and both temperature changes were asymmetrical. There was a consistent temperature drop during thinking, with a consistent rise after thinking ceased. Heat loss from superficial vessels of the buccal region and nasal mucosa to the ambient air was evident which caused lowering of the venous blood temperature flowing towards the cavernous sinus. This drop in blood temperature of angularis oculi veins coincided with increased brain metabolism and heat production occasioned by an increase in the level of mental activity and oxygen utilization.
这项初步研究描述了一种与精神活动相关的、用于研究大脑半球优势化的非侵入性、低成本方法。它支持了血液在脑温控制中具有体温调节作用的概念。在精神活动期和精神休息期测量了左右眼内角静脉的温度，且两种温度变化都是不对称的。思考期间温度持续下降，思考停止后则持续上升。颊部区域和鼻黏膜浅表血管向周围空气的散热明显，这导致流向海绵窦的静脉血温度降低。眼内角静脉血温的下降与精神活动水平和氧利用增加所引起的脑代谢和产热增加相吻合。
