Three intensities of patterned flash were used to elicit visually evoked potentials (VEPs) from central scalp of 220 healthy males aged 4-90 years. Intensities were based on visual thresholds. VEP components from children and oldsters were generally larger than those of subjects of intermediate ages and, in response to increased flash intensity, demonstrated greater amplitude enhancement. This pattern of age changes is thought to reflect decreased cortical inhibition in the young and the old with inhibitory capacity being maximal during late adolescent and early adult years. Hemispheric asymmetries were observed. VEP amplitudes from the right hemisphere were larger than those from the left and demonstrated a greater amplitude augmentation to brighter flashes.
使用三种强度的图案闪光从220名年龄在4至90岁的健康男性的头皮中央引出视觉诱发电位（VEP）。强度基于视觉阈值。儿童和老年人的VEP成分通常大于中年受试者的VEP成分，并且随着闪光强度的增加，表现出更大的振幅增强。这种年龄变化模式被认为反映了年轻人和老年人皮质抑制的降低，而抑制能力在青少年晚期和成年早期最大。观察到半球不对称性。右半球的VEP振幅大于左半球的VEP振幅，并且对更亮的闪光表现出更大的振幅增加。
