Abstract

Cerebral impedance changes (F changes) indicating cerebral blood flow were studied in 17 children aged 6-11 years and in 10 normal adults. At rest, large values were found in children, who never exhibited the 'hyperfrontality' pattern of the adults. Reading induced an F increase in both the dominant and non-dominant hemispheres, in contrast with a larger increase in the dominant hemisphere in adults. A spatial test was designed in adults which triggered a larger increase in the non-dominant hemisphere.

摘要

对17名6至11岁儿童和10名正常成年人进行了研究，以观察指示脑血流量的脑阻抗变化（F变化）。静息时，儿童的F值较大，且儿童从未表现出成人才有的“额叶优势”模式。阅读会使优势半球和非优势半球的F值均升高，这与成年人优势半球F值升高幅度更大形成对比。在成年人中设计了一项空间测试，该测试引发非优势半球F值有更大幅度的升高。
