一般智力的神经机制

Neural Mechanism of General Intelligence

本文探讨支持一般智力的几个脑部位和脑特征:具体归纳支持一般智力的几个特定脑部位,即脑的大小、额区和顶区、白质和灰质等;进一步揭示这些脑区神经网状联接的整体效率是支持一般智力的主要因素,尤其在额顶区,且高智力者的该特征更为明显;同时指出未来研究中,纵向追踪是探讨这个问题的有效手段,且有必要将来自不同神经成像技术的数据标准化。

The present paper is a review of the studies on the correlation between general intelligence and several brain regions. A lot of empirical studies have found that general intelligence is closely related to such factors as the size of the brain and the activities in and function of prefrontal cortex,parietal cortex,gray mater and white matter. The efficiency of communication within brain regions,especially the frontoparietal network,is the key biological basis for general intelligence. This effect is more obvious on people with high intelligence. The future research in this field should involve longitudinal studies of brain and cognitive development with a large sample size and the standardization of the data collected by employing different neuroimaging technologies.
