Zhou2020 — 7-day motor imagery BCI EEG dataset (repackaged)

Re-hosted EEG data from Zhou et al. (2021), originally deposited on IEEE DataPort (DOI: 10.21227/f1c7-7x89) under a CC BY 4.0 license. The original multi-subject ZIP archives have been split into per-subject ZIPs with a clean session/run directory structure. Paper Q. Zhou, J. Lin, L. Yao, Y. Wang, Y. Han, K.

背景概述

这是一个重新打包的7天纵向运动想象脑电图数据集，基于Zhou等人2021年的研究，包含20名健康受试者执行左手、右手、双脚和空闲四种想象任务的脑电数据。数据由Neuroscan SynAmps2系统以500Hz采样率采集，按受试者-会话-运行层次结构存储为NPZ格式，旨在支持脑机接口算法的开发和评估，许可证为CC BY 4.0。
