脑电信号分析的一种新的图论方法

A Tutorial on Graph Theory for Brain Signal Analysis

Imperial College London(伦敦帝国学院)

Nikolaos Laskaris, Dimitrios A. Adamos, Anastasios Bezerianos

摘要:

本教程涉及使用图论概念分析大脑信号。出于教学目的,它分为两个部分:理论和应用。在第一部分中,我们首先介绍了一些基本元素,从图论和词干算法工具,可以用于数据分析的目的。接下来,我们将描述这些概念是如何适应处理不断变化的连接,并获得深入了解网络重组。最后,信号驻留在一个给定的图形的概念进行了介绍,并从图形信号处理(GSP)的新兴领域提供的元素。第二部分作为前面描述的工具和技术的实用演示。它是基于分析包含来自视觉ERP范例的单次试验响应的多试验数据集。本文最后简要概述了即将在不久的将来塑造大脑信号处理的图论最新趋势,并对分析连续模式神经记录的图论方法的相关性进行了更一般的讨论。

英文摘要:

This tutorial paper refers to the use of graph-theoretic concepts for analyzing brain signals. For didactic purposes it splits into two parts: theory and application. In the first part, we commence by introducing some basic elements from graph theory and stemming algorithmic tools, which can be employed for data-analytic purposes. Next, we describe how these concepts are adapted for handling evolving connectivity and gaining insights into network reorganization. Finally, the notion of signals residing on a given graph is introduced and elements from the emerging field of graph signal processing (GSP) are provided. The second part serves as a pragmatic demonstration of the tools and techniques described earlier. It is based on analyzing a multi-trial dataset containing single-trial responses from a visual ERP paradigm. The paper ends with a brief outline of the most recent trends in graph theory that are about to shape brain signal processing in the near future and a more general discussion on the relevance of graph-theoretic methodologies for analyzing continuous-mode neural recordings.
