EEG and EMG Dataset for Analyzing Movement-Related Cortical Potentials in Hand Gesture Tasks

This database contains recordings of electroencephalography (EEG) and electromyography (EMG) obtained during the detection of movement-related cortical potentials (MRCPs) in healthy subjects. The experimental protocol consisted of performing a voluntary right-hand movement (fist clenching). EEG signals were acquired using 32 electrodes placed according to the international 10-10 system, with a particular focus on the fronto-central regions (FC3, FC1, FCz, C3, C1, Cz, CP3, CP1, and CPz). Complementary EMG recordings were obtained from the right forearm muscles to validate the presence and characteristics of motor activity. This database is intended to support research in brain-computer interfaces (BCI) and the characterization of MRCPs.

本数据库收录了健康受试者在运动相关皮层电位（Movement-Related Cortical Potentials, MRCPs）检测过程中采集的脑电图（Electroencephalography, EEG）与肌电图（Electromyography, EMG）数据。实验方案为受试者完成自主右手握拳动作。脑电图信号采用基于国际10-10系统布设的32个电极采集，重点覆盖额中央区域（包括FC3、FC1、FCz、C3、C1、Cz、CP3、CP1及CPz）。研究人员同步采集右侧前臂肌肉的肌电图信号，以验证运动活动的存在及其特征。本数据库旨在为脑机接口（Brain-Computer Interfaces, BCI）相关研究以及运动相关皮层电位的特征分析提供数据支持。
