自发性眨眼率是基于神经药理学和临床研究的中枢多巴胺活性的推定指标，其与认知活动和行为状态有关。虽然已经研究了许多物种，但很少有研究人员研究人类婴儿的自发眨眼。在喂养之前、期间和之后或在注意视觉刺激期间观察10至12周龄的人类婴儿。婴儿每分钟自发眨眼几次，在喂食期间和出现新的视觉刺激后，他们的眨眼率增加。在受控条件下自发性眨眼率的这些系统性变化表明，自发性眨眼率可能反映中枢神经系统活动的可靠变化，中枢神经系统活动是对突出或新颖刺激的行为和认知反应的基础。(C)2004 Wiley Periodicals，Inc.
The rate of spontaneous eye blinking, a putative index of central dopamine activity based on neuropharmacological and clinical research, has been linked to cognitive activity and behavioral state. Although many species have been studied, few researchers have examined spontaneous eye blinking in human infants. Human infants between 10 and 12 weeks of age were observed before, during, and after a feeding or during attention to visual stimuli. Infants blinked spontaneously several times per minute, and their blinking rate increased during feeding and after the appearance of new visual stimuli. These systematic changes in the rate of spontaneous blinking under controlled conditions suggest that spontaneous blinking rate may reflect reliable variation in central nervous system activity that underlies behavioral and cognitive responses to salient or novel stimuli.
