Multi-channel EEG recordings during a sustained-attention driving task (pre-processed dataset)

This project adopted an event-related lane-departure paradigm in a virtual-reality (VR) dynamic driving simulator to quantitatively measure brain EEG dynamics along with the fluctuation of task performance throughout the experiment.All subjects were required to have driving license. None of the participants had a history of psychological disorders. All participants were instructed to sustain their attention to perform the task during the experiment, and the 32-ch EEG signals and the vehicle position were recorded simultaneously.Prior to the experiment, all participants completed a consent form stating their clear understanding of the experimental protocol which had been approved by Institutional Review Broad of Taipei Veterans General Hospital, Taiwan.<b>Experiment:</b> <br>All subjects participated in the sustained-attention driving experiment for 1.5 hours in the afternoon (13:00-14:00) after lunch, and all of them were asked to keep their attention focused on driving during the entire period. There was no break or resting session. At the beginning of the experiment (without any recordings), a five-minute pre-test was performed to ensure that every subject understood the instructions and they did not suffer from simulator-induced nausea. To investigate the effect of kinesthesia on brain activity in the sustained-attention driving task, each subject was asked to participate at least two driving sessions on different days. Each session lasted for about 90 min. One was the driving session with a fixed-based simulator but with no kinesthetic feedback, so subject had to monitor the vehicle deviation visually from the virtual scene.The other driving session involved a motion-based simulator with a six degree-of-freedom Stewart platform to simulate the dynamic response of the vehicle to the deviation event or steering. The visual and kinesthetic inputs together aroused the subject to attend to the deviation event and take action to correct the driving trajectory Data Requirement.A wired EEG cap with 32 Ag/AgCl electrodes, including 30 EEG electrodes and two reference electrodes (opposite lateral mastoids) was used to record the electrical activity of the brain from the scalp during the driving task. The EEG electrodes were placed according to a modified international 10-20 system. The contact impedance between all electrodes and the skin was kept &lt;5kΩ. The EEG recordings and the vehicle trajectory amplified by Scan SynAmps2 Express system (Compumedics Ltd., VIC, Australia) were digitized at 500 Hz (resolution: 16 bits) simultaneously.

本研究采用虚拟现实（Virtual Reality, VR）动态驾驶模拟器中的事件相关车道偏离范式，对整个实验过程中的脑电（Electroencephalogram, EEG）动态变化与任务绩效波动进行定量测量。所有受试者均需持有驾驶执照，且无精神疾病病史。实验过程中，要求所有参与者持续保持注意力以完成任务，并同步记录32通道脑电信号与车辆位置数据。实验前，所有参与者均签署知情同意书，明确知晓实验方案，该实验流程已通过中国台湾台北荣民总医院伦理审查委员会（Institutional Review Board, IRB）的批准。<b>实验流程：</b> <br>所有受试者于午餐后下午（13:00-14:00）参与时长1.5小时的持续性注意力驾驶实验，全程无休息或休整环节。实验正式开始前（无记录阶段）先进行5分钟预测试，以确认所有受试者理解实验指导，且未出现模拟器诱发的恶心症状。为探究动觉反馈对持续性注意力驾驶任务中脑活动的影响，要求每位受试者在不同日期至少参与两次驾驶实验，单次实验时长约90分钟。其中一次为固定基座模拟器驾驶实验，无动觉反馈，受试者仅需通过虚拟场景视觉监测车辆偏离情况；另一次为搭载六自由度Stewart平台的运动基座模拟器实验，可模拟车辆对偏离事件或转向操作的动态响应，结合视觉与动觉输入唤醒受试者对偏离事件的注意力，并采取动作修正驾驶轨迹。数据采集要求：本研究采用配备32个Ag/AgCl电极的有线脑电帽，包含30个脑电电极与2个参考电极（放置于双侧乳突），用于采集驾驶任务期间头皮脑电活动。脑电电极按照改良的国际10-20系统排布，所有电极与皮肤间的接触阻抗均控制在5kΩ以下。通过Scan SynAmps2 Express系统（澳大利亚Compumedics有限公司，维多利亚州）放大的脑电记录与车辆轨迹数据，以500Hz采样率（分辨率：16比特）同步数字化。
