While it has been shown that alpha frequency increases over development (Stroganova et al., 1999), a precise trajectory has not yet been specified, making it challenging to constrain theories linking alpha rhythms to perceptual development. We conducted a comprehensive review of studies measuring resting-state occipital peak alpha frequency (PAF, the frequency exhibiting maximum power) from birth to 18 years of age. From 889 potentially relevant studies, we identified 40 reporting PAF (109 samples; 3882 subjects). A nonlinear regression revealed that PAF increases quickly in early childhood (from 6.1 Hz at 6 months to 8.4 Hz at 5 years) and levels off in adolescence (9.7 Hz at 13 years), with an asymptote at 10.1 Hz. We found no effect of resting state procedure (eyes-open versus eyes-closed) or biological sex. PAF has been implicated as a clock on visual temporal processing, with faster frequencies associated with higher visual temporal resolution. Psychophysical studies have shown that temporal resolution reaches adult levels by 5 years of age (Freschl et al., 2019, 2020). The fact that PAF reaches the adult range of 8-12 Hz by that age strengthens the link between PAF and temporal resolution.
虽然已经证明阿尔法频率在发育过程中会增加（Stroganova 等人，1999 年），但尚未确定精确的轨迹，这使得将阿尔法节律与感知发育联系起来的理论受到限制。我们对从出生到 18 岁测量静息状态枕部峰值阿尔法频率（PAF，表现出最大功率的频率）的研究进行了全面综述。从 889 篇潜在相关的研究中，我们确定了 40 篇报告 PAF 的研究（109 个样本；3882 名受试者）。非线性回归显示，PAF 在幼儿期迅速增加（从 6 个月时的 6.1 Hz 增加到 5 岁时的 8.4 Hz），并在青春期趋于平稳（13 岁时为 9.7 Hz），其渐近值为 10.1 Hz。我们没有发现静息状态程序（睁眼与闭眼）或生物性别对 PAF 的影响。PAF 被认为是视觉时间处理的时钟，较快的频率与较高的视觉时间分辨率相关。心理物理学研究表明，时间分辨率在 5 岁时达到成人水平（Freschl 等人，2019 年，2020 年）。到那个年龄，PAF 达到成人范围 8-12 Hz，这加强了 PAF 与时间分辨率之间的联系。
