We investigated the development of the magnitude and phase alignment of steady-state visual evoked potentials induced by 5 Hz intermittent photic stimulation in 46 children (3 to 16 years) and 8 adults, as a function of age. We found that, over the occipital region, magnitude values were the highest in 8-11-year old children, but decreased with age over all other cerebral regions. Phase alignment values increased with age over the occipital, parietal and frontal cerebral regions. We interpret these findings in terms of the development of functional interactions between different cortical areas involved in the processing of visual stimuli.
我们研究了 46 名儿童（3 至 16 岁）和 8 名成人在 5Hz 间歇性光刺激下诱发的稳态视觉诱发电位的幅度和相位对齐的发展情况，作为年龄的函数。我们发现，在枕区，幅度值在 8 至 11 岁的儿童中最高，但在所有其他脑区随年龄增长而降低。相位对齐值随年龄在枕部、顶叶和额叶脑区增加。我们根据处理视觉刺激的不同皮质区域之间功能相互作用的发展来解释这些发现。
