The representation of spatiotemporal pattern of brain electrical activity is an important issue in the research of neural assemblies. This paper describes methods of parametric 3D head or brain modeling and its corresponding interpolation for functional imaging based on brain waves. The 3D interpolation method is an extension of cortical imaging technique. It can be used with features of either transformed domains or higher order statistics of brain waves on realistic head or brain models. The simulating result suggests that it is a better method in comparison with the global nearest neighbor technique. With those techniques, an example of brainwave imaging was given using partial coherence of event-related potentials estimated by multivariate autoregressive model.
脑电活动时空模式的表示是神经集合研究中的一个重要问题。本文描述了基于脑电波的功能性成像的参数化三维头部或脑部建模方法及其相应的插值方法。三维插值方法是皮质成像技术的扩展。它可以与现实头部或脑部模型上脑电波的变换域特征或高阶统计特征一起使用。模拟结果表明,与全局最近邻技术相比,它是一种更好的方法。利用这些技术,给出了一个使用多元自回归模型估计的事件相关电位的部分相干性进行脑电波成像的例子。
