Retinal and cortical responses to pattern reversal stimulation were recorded simultaneously in three human infants of average age 3.5 months and two adults of average age 28.5 years. The relative power of retinal signals as a function of spatial frequency for both adults and infants was very similar and extrapolated to a threshold of about 30 c/deg [6/6 (20/20)] as did the relative power of the adult cortical signal. The infant cortical signal was relatively more attenuated at higher spatial frequencies and extrapolated to a threshold of 8.5 c/deg [6/22.2 (20/74)]. A greater relative maturity of retinal as compared with cortical neural function in 3.5-month-olds is inferred.
在三名平均年龄为3.5个月的人类婴儿和两名平均年龄为28.5岁的成年人中，同时记录了视网膜和皮质对模式反转刺激的反应。成人和婴儿视网膜信号的相对功率作为空间频率的函数非常相似，并且外推到约30周/度[6/6 (20/20)]的阈值，成人皮质信号的相对功率也是如此。婴儿皮质信号在较高空间频率下相对更衰减，外推到8.5周/度[6/22.2 (20/74)]的阈值。由此推断，3.5个月大婴儿的视网膜神经功能与皮质神经功能相比相对更成熟。
