目前分析的目标是检查3个月至8岁的皮质听觉诱发电位(CAEP)的成熟度。检查额上正-负-正序列(P_1、N_2、P_2)和时间部位、负-正-负序列(可能是T-复合体的Na、Ta、Tb)。记录了63个头皮部位到250毫秒元音的事件相关电位。测量左右额叶(FZ附近)和左右颞叶(T7、T8)的波幅和潜伏期。此外，从全局场功率(GFP)中选择最大的峰值(通常对应于P1)。结果显示，所有年龄段的额叶部位都有一个大的正峰(P1)。N_2出现在6个月龄，P2出现在8~30个月龄。这些峰的潜伏期呈指数下降，其中以P1下降最快。对于波幅，只有P1与年龄有明显的关系，以某种线性的方式变得更积极。在14个月以上的儿童中，在左侧和右侧的颞区只有一个负峰，可能是钠，峰值出现在100到200毫秒之间。额叶部位的P_1测量与钠峰潜伏期呈中度相关。时间负峰潜伏期表现出与P1峰不同的成熟时间进程(本质上是线性的)，表明至少部分独立。除Ta出现在7岁儿童外，多数年龄组儿童的Ta峰(阳性峰)和Tb峰(阴性峰)不一致，出现在Na之后，峰值出现在120~220ms之间。未来的研究，包括对刺激因素的操纵和建模技术的使用，将需要解释当前研究中时间部位测量的明显、持久的成熟。
The goal of the current analysis was to examine the maturation of cortical auditory evoked potentials (CAEPs) from three months of age to eight years of age. The superior frontal positive-negative-positive sequence (P1, N2, P2) and the temporal site, negative-positive-negative sequence (possibly, Na, Ta, Tb of the T-complex) were examined. Event-related potentials were recorded from 63 scalp sites to a 250- ms vowel. Amplitude and latency of peaks were measured at left and right frontal sites (near Fz) and at left and right temporal sites (T7 and T8). In addition the largest peak (typically corresponding to P1) was selected from global field power (GFP). The results revealed a large positive peak (P1) easily identified at frontal sites across all ages. The N2 emerged after 6 months of age and the following P2 between 8 and 30 months of age. The latencies of these peaks decreased exponentially with the most rapid decrease observed for P1. For amplitude, only P1 showed a clear relationship with age, becoming more positive in a somewhat linear fashion. At the temporal sites only a negative peak, which might be Na, was clearly observed at both left and right sites in children older than 14 months and peaking between 100 and 200 ms. P1 measures at frontal sites and Na peak latencies were moderately correlated. The temporal negative peak latency showed a different maturational timecourse (linear in nature) than the P1 peak, suggesting at least partial independence. Distinct Ta (positive) and Tb (negative) peaks, following Na and peaking between 120 and 220 ms were not consistently found in most age groups of children, except Ta which was present in 7 year olds. Future research, which includes manipulation of stimulus factors, and use of modeling techniques will be needed to explain the apparent, protracted maturation of the temporal site measures in the current study.
