最近计算能力的激增导致了广泛的方法发展和先进的信号处理技术，这些技术在神经科学中起着关键作用。特别是，脑信号分析领域出现了对大数据集进行多维分析的强烈趋势，例如，对高时空分辨率记录进行单次试验时频分析。在这里，我们描述了免费的ELAN软件包，它提供了广泛的电生理数据信号分析工具，包括头皮脑电图（EEG）、脑磁图（MEG）、颅内脑电图和局部场电位（LFPs）。ELAN工具箱基于里昂脑动力学和认知实验室25年的方法学发展，并在许多论文中使用，包括探索人类诱发和诱导振荡活动的脑电图数据的时频分析的第一项研究。本文概述了ELAN的概念和功能，强调了它的特点，并描述了它与其他工具箱的互补性和互操作性。
The recent surge in computational power has led to extensive methodological developments and advanced signal processing techniques that play a pivotal role in neuroscience. In particular, the field of brain signal analysis has witnessed a strong trend towards multidimensional analysis of large data sets, for example, single-trial time-frequency analysis of high spatiotemporal resolution recordings. Here, we describe the freely available ELAN software package which provides a wide range of signal analysis tools for electrophysiological data including scalp electroencephalography (EEG), magnetoencephalography (MEG), intracranial EEG, and local field potentials (LFPs). The ELAN toolbox is based on 25 years of methodological developments at the Brain Dynamics and Cognition Laboratory in Lyon and was used in many papers including the very first studies of time-frequency analysis of EEG data exploring evoked and induced oscillatory activities in humans. This paper provides an overview of the concepts and functionalities of ELAN, highlights its specificities, and describes its complementarity and interoperability with other toolboxes.
