Cerebral Function Monitor (CFM) recordings were performed on 10 term and 19 preterm healthy infants. Term infants were monitored once, while preterm infants were followed serially. Forty-six recordings were made on 7, 14, 16 and 9 occasions in the age groups 30-31, 32-33, 34-35 and 36-37 weeks. All infants were examined clinically at 18 months of age and found healthy. By drawing weighted lines derived from the lower and upper limits of the CFM traces, mean values of minimum and maximum cerebral activity were calculated for the different age groups. In the term infants different CFM traces were identified corresponding to quiet sleep and active sleep. In the preterm infants a similar cyclic variability of the CFM trace was noted. A gradual increase in the minimum cerebral activity was found with increasing gestational age, resulting in a gradual narrowing of the trace.
对10名足月儿和19名早产儿进行了脑功能监测（CFM）记录。足月儿监测一次，而早产儿则进行连续跟踪。在30 - 31周、32 - 33周、34 - 35周和36 - 37周年龄组中，分别在7次、14次、16次和9次记录中进行了46次记录。所有婴儿在18个月大时进行临床检查，结果均健康。通过绘制从CFM轨迹下限和上限得出的加权线，计算出不同年龄组脑活动最小值和最大值的平均值。在足月儿中，识别出了与安静睡眠和活跃睡眠相对应的不同CFM轨迹。在早产儿中，也注意到CFM轨迹有类似的周期性变化。随着胎龄增加，脑活动最小值逐渐增加，导致轨迹逐渐变窄。
