2022年8月15日 · To quantify and generalize ERD/S, the concept of event-related spectral perturbation (ERSP) (Grandchamp and Delorme, 2011) is introduced. ERSP describes the relative changes in the EEG amplitude spectrum of similar events in the experimental trials, and is computed using a divisive baseline and discrete sliding window.

2019年3月24日 · 越来越多的研究已经证实：事件相关去同步化（event-related desynchronization，ERD）和事件相关同步化（event related synchronization，ERS）是研究脑功能信号有用的分析方法。 本文结合现有的文献报道，对ERD/ERS的概况、量化方法以及临床相关研究进行综述。 1.ERD/ERS概况. 随着脑电信号记录及分析的发展，PFURTSCHELLER和ANDREW在1999年证实在单手准备和执行运动时，对侧感觉运动皮质脑电信号中α频 …

2025年3月23日 · We hope that this dataset will significantly advance MI-BCI research, particularly in addressing cross-session and cross-subject challenges. ... ERSP is a method used in EEG analysis to examine ...

2023年9月5日 · We present and share a large database containing electroencephalographic signals from 87 human participants, collected during a single day of brain-computer interface (BCI) experiments, organized...

2017年8月21日 · Recent advances in non-invasive brain-computer interface (BCI) technologies have shown the feasibility of neural decoding for both users’ gait intent and continuous kinematics. However, the...

基于言语想象的脑机接口（Brain⁃Computer Interface，BCI）在一定程度上可以帮助言语障碍患者恢复语言沟通能力，也是目前较新颖的一种范式，凭借其对被试友好、自由度高等优点逐渐受到关注，但将不同言语想象范式之间的神经机制差异和分类效果进行对比的 ...

2021年4月6日 · Fast Fourier transform (FFT) and event-related spectral perturbation (ERSP) were used to extract EEG frequency domain response and time-frequency features. The multi-frequency power changes were calculated at alpha (8～14 Hz), low beta (15～24 Hz) and high beta (25～35 Hz) bands.

对脑机接口 (bci) 的研究为计算机以直接的方式理解人类思想提供了可能性，从而促进了交流。作为 bci 研究的一个分支，运动想象 (mi) 技术分析大脑信号并在康复、临床应用、娱乐和系统控制等诸多方面帮助人们。

2022年8月16日 · In this study, an imagery experiment consisting of four kinds of right-hand movements (gripping, opening, pronation, and supination) was designed. Then a novel feature, namely, clustered feature was proposed based on the event-related spectral perturbation (ERSP) calculated from the EEG signal.
