Surrey cEEGrid sleep data set

Surrey sleep data set **Overview** This dataset was collected as part of a research project on wearable sleep monitoring which took place in spring 2017. The data set contains nightly EEG recordings from 20 healthy participants ('subjects'). Some recordings are full polysomnography (PSG) measurements, others are cEEGrid measurements. Most subjects have both PSG and ceegrid recordings from the same night, though a few are missing one or the other. **Format** The dataset is formatted according to the Brain Imaging Data Structure. See the 'dataset_description.json' file for the specific BIDS version used. The EEG data format chosen is the '.set' format of EEGLAB. For more information, see the following link: https://bids-specification.readthedocs.io/en/stable/01-introduction.html **Task description** The patient performed no tasks. The recording equipment was mounted immediately prior to bedtime, and the recordings took place at the sleep laboratory of the Surrey Clinical Research Centre. Note that due to a miscommunication during the study, alignment information between cEEGrid and PSG recordings has not been saved. This means that to obtain a useful comparison between the two methods, for instance to align the manual scoring with the cEEGrid recordings, some post processing has to be performed. In the derivative dataset, 'aligned1', we have shared our own best attempt at alignment. The data set was previously described in the paper 'Machine-learning-derived sleep–wake staging from around-the-ear electroencephalogram outperforms manual scoring and actigraphy', Mikkelsen et al 2018, https://doi.org/10.1111/jsr.12786 **Contact** For questions regarding this data set, contact: Kaare Mikkelsen, [e-mail], https://orcid.org/0000-0002-7360-8629萨里睡眠数据集（Surrey Sleep Dataset） ## 概述 本数据集采集自2017年春季开展的可穿戴睡眠监测研究项目。 数据集包含20名健康受试者的夜间脑电（Electroencephalogram, EEG）记录。部分记录为完整多导睡眠图（Polysomnography, PSG）测量结果，其余为cEEGrid测量结果。多数受试者在同一夜间同时拥有PSG与cEEGrid记录，但少数受试者缺失其中一类记录。 ## 数据格式 本数据集遵循脑成像数据结构（Brain Imaging Data Structure, BIDS）格式规范，具体使用的BIDS版本可参阅`dataset_description.json`文件。所选脑电数据格式为EEGLAB的`.set`格式。 更多信息可参阅以下链接： https://bids-specification.readthedocs.io/en/stable/01-introduction.html ## 任务说明 受试者未执行任何任务。记录设备于就寝前即刻安装，录制工作在萨里临床研究中心的睡眠实验室开展。 注意：由于研究期间沟通失误，cEEGrid与PSG记录间的对齐信息未被保存。这意味着若要对两种测量方法开展有效对比（例如将人工睡眠分期评分与cEEGrid记录对齐），需进行一定的后处理操作。在衍生数据集`aligned1`中，我们已分享了自行尝试的最优对齐方案。 本数据集曾在论文《基于耳周脑电图的机器学习睡眠-觉醒分期优于人工评分与活动记录仪》（Mikkelsen等，2018年，https://doi.org/10.1111/jsr.12786）中被详细阐述。 ## 联系方式 如有关于本数据集的疑问，请联系：卡尔·米凯尔森（Kaare Mikkelsen），电子邮箱：[e-mail]，ORCID标识：https://orcid.org/0000-0002-7360-8629
