Abstract

This pilot EEG mapping study was designed to explore thinking processes using complex mental imagery and thought processes. EEG was recorded with 19 electrodes (10/20 system against averaged ear lobe signals) while volunteers (n = 42) performed two separate tasks: visualization of an abstract concept and interpretation of a painting. Average spectral parameters such as amplitude, local and interhemispheric coherences were computed for five frequency bands (theta, alpha, beta 1, 2 and 3). Results indicate that the frontal regions are strongly involved during these tasks as evidenced by coherence changes. Changes are also present in temporal, parietal and occipital regions and are discussed in relation to information processing with the frontal regions considering the different cognitive functions required by the tasks.

摘要

这项脑电图映射初步研究旨在利用复杂心理意象和思维过程探索思维过程。在志愿者（n = 42）执行两项不同任务时，用19个电极（10/20系统，以平均耳垂信号为参考）记录脑电图：对一个抽象概念进行可视化以及对一幅画作进行解读。计算了五个频段（θ波、α波、β1波、β2波和β3波）的平均频谱参数，如振幅、局部和半球间相干性。结果表明，在这些任务中额叶区域有强烈参与，这一点通过相干性变化得到证明。颞叶、顶叶和枕叶区域也有变化，并结合任务所需的不同认知功能，就与额叶区域的信息处理相关方面进行了讨论。
