supporting data for " Accessing the immature brain--explore electrophysiological markers for brain maturity and the risk of neurodevelopmental disorders in preterm born children"

This is the supporting data for my MPhil thesis entitled " Accessing the immature brain--explore electrophysiological markers for brain maturity and the risk of neurodevelopmental disorders in preterm born children" This study investigated the correlation between resting-state EEG profile and cognitive/behaviour performance in preschool children (including children born preterm and at term). All EEG and behavioural/questionnaire data are collecetd in Duchess of Kent Children’s Hospital Child Assessment Centre (DKCAC) and Queen Marry Hospital (QM). In this dataset , behavioural/cognitive test scores, as well as questionnaire responses of the participated chilren are provided. Both raw EEG recordings and processed EEG data are also provided. For the processed EEG data, both aperiodic component (offset and expotent) and traditional band power (absolute and relative) are provided. IRB approval code UW 20-455. Directory of Files: A. Filename: Preterm_EEG_database Short description: raw questionaire data B. Filename: EEG_prem_analysis Short description:Combined dataset with EEG parameters and averaged questionaire data C. Filename: EEG_data Short description:raw EEG data for generating the EEG parameters, MATLAB (2012 or above) and EEGLAB package is required to process those raw data. The MATLAB processing code is also in the file; while again MATLAB EEGLAB is required to run this script. File C 'EEG_data' is for EEG experts to examine the raw EEG data; for processed EEG data, please refer to file B 'EEG_prem_analysis'.本数据集为本人哲学硕士（Master of Philosophy, MPhil）学位论文《访问未成熟大脑——探究早产儿童脑成熟电生理标志物及神经发育障碍风险》的配套研究数据。本研究针对学龄前儿童（涵盖早产及足月出生儿童）的静息态脑电图（electroencephalogram, EEG）特征与认知/行为表现之间的相关性展开调查。所有脑电图及行为/问卷数据均采集自肯特公爵夫人儿童医院儿童评估中心（Duchess of Kent Children’s Hospital Child Assessment Centre, DKCAC）与玛丽女王医院（Queen Marry Hospital, QM）。本数据集包含受试儿童的行为/认知测试得分及问卷反馈结果，同时提供原始脑电图记录与预处理后的脑电图数据。其中预处理后的脑电图数据涵盖非周期分量（偏移量与指数）以及传统频带功率（绝对功率与相对功率）。本研究已获得机构审查委员会（Institutional Review Board, IRB）批准，审批编号为UW 20-455。 文件目录如下： A. 文件名：Preterm_EEG_database，简短描述：原始问卷数据 B. 文件名：EEG_prem_analysis，简短描述：整合脑电图参数与平均问卷数据的复合数据集 C. 文件名：EEG_data，简短描述：用于生成脑电图参数的原始脑电图数据，需使用MATLAB（2012及以上版本）与EEGLAB工具包进行处理，配套的MATLAB处理代码亦包含于该文件中，运行该脚本同样需要依赖MATLAB与EEGLAB。文件C "EEG_data" 供脑电图领域专家审查原始脑电图数据使用；若需获取预处理后的脑电图数据，请参阅文件B "EEG_prem_analysis"。
