Functional near-infrared spectroscopy (fNIRS)is a brain-imaging technology used to reveal brain activity by measuring blood oxygenation. Using fNIRS we measured activity in the left prefrontal lobe of 8-14 month-old infants as they crawled or were pushed in a stroller and as they were given a passive attention task or an active executive function (EF) task. For each task, we measured peak total hemoglobin concentration and peak Oxy relative to baseline. Results revealed differences in peak Oxy levels for crawling vs. strolling and between the EF and passive cognitive tasks, with total hemoglobin greater for the EF task than the passive attention task. These results support the theoretical view that both active locomotion and EF engage the prefrontal cortex (PFC) during early development.
功能近红外光谱技术（fNIRS）是一种脑成像技术，通过测量血液氧合作用来揭示大脑活动。我们使用fNIRS测量了8至14个月大婴儿在爬行、被推着坐在婴儿车中、接受被动注意力任务或主动执行功能（EF）任务时左前额叶的活动。对于每项任务，我们测量了相对于基线的总血红蛋白浓度峰值和氧合血红蛋白峰值。结果显示，爬行与坐婴儿车时以及EF任务和被动认知任务之间的氧合血红蛋白峰值水平存在差异，EF任务中的总血红蛋白高于被动注意力任务。这些结果支持了这样一种理论观点，即在早期发育过程中，主动运动和EF均会激活前额叶皮质（PFC）。
