摘要

采用基于EEGLAB和Matlab工具箱的测量投影分析(MPA)方法,分析脑电信号源在头皮电极上的投影,这些信号源负责头皮电极上的测量电位。这些投影是基于概率多主体算法,抛弃了不同的独立成分簇的概念。它逐个体素地检查具有事件相关独立组件的大脑区域,这些组件通过概率密度表示在受试者之间表现出统计上显著的一致性。神经元源位置负责通过测量电位在不同脑区产生电流。研究了不同年龄组的视觉诱发电位(VEP)源的投射。结果表明,随着年龄的增长,预测结果略有不同。这些发现代表了成熟水平,重新把握了大脑和视觉通路随年龄的发展。

Measure Projection Analysis of VEP localization neuron generator
Measure Projection Analysis (MPA) method based on EEGLAB and Matlab Toolbox is used to analyze the projections of brain signal sources that are responsible for the measured potentials at the scalp electrodes. These projections are based on probabilistic multi subject algorithm abandoning the notion of distinct independent component clusters. It examines voxel by voxel for brain regions having event related independent components process dynamics that exhibit statistically significant consistency across subjects by probability density representation. Neuron source locations are responsible in generating current in different brain regions through the measured potentials. The projections of visual evoked potentials (VEP) sources in different age groups are investigated. The result shows a slight difference in the projections with respect to the age. These findings represent the maturity level and re-grasp the development of brain and visual pathway with age.
