MI-hBCI dataset

In this study, we collected EEG and EMG data from 16 subjects during the MI process and constructed a homemade MI-hBCI dataset. The participants included 10 males (mean age: 22.3±3.1 years) and 6 females (mean age: 22.1±2.4 years). All the subjects were right-handed, had normal vision, and had no motor impairment; all the participants signed a consent form and were informed of the experimental procedure and precautions before the experiment. The MI-hBCI dataset contains three categories of MI movements: left-handed movements, right-handed movements, and the resting state. We conducted 30 10-second MI experiments with each subject for a total of 420 sessions. The specific experimental procedure is shown in Fig. 3. Among the outputs, the EEGs were based on the international 10-20 system [49], which consists of 32 channels with a sampling frequency of 500 Hz; four EMG electrodes were located in the left biceps brachii, left triceps brachii, right biceps brachii, and right triceps brachii, with a sampling frequency of 500 Hz.

本研究共收集了16名受试者在运动想象（Motor Imagery，MI）过程中的脑电图（Electroencephalogram，EEG）与肌电图（Electromyography，EMG）数据，并构建了自制的运动想象脑机接口（Motor Imagery human Brain-Computer Interface，MI-hBCI）数据集。受试者中包含10名男性（平均年龄22.3±3.1岁）与6名女性（平均年龄22.1±2.4岁）。所有受试者均为右利手，视力正常且无运动功能障碍；所有参与者在实验前均签署了知情同意书，并了解实验流程与注意事项。该MI-hBCI数据集包含三类运动想象动作：左手动作、右手动作以及静息态。本研究为每名受试者开展了30次时长10秒的运动想象实验，总实验场次共计420次。具体实验流程如图3所示。本次采集的脑电图信号基于国际10-20系统[49]，共包含32个通道，采样频率为500 Hz；4个肌电图电极分别放置于左侧肱二头肌、左侧肱三头肌、右侧肱二头肌以及右侧肱三头肌，采样频率同样为500 Hz。
