Ear-EEG Sleep Monitoring 2023 (EESM23)

Ear-EEG Sleep Monitoring 2023 (EESM23) data set

**Overview**

This dataset was collected as part of a research project on ear-EEG sleep monitoring which took place in 2020-2022.

The data set contains nightly EEG recordings from 10 healthy participants ('subjects'). The first two recordings consist of polysomnogrpahy (PSG) measurements and ear-EEG measurements. The remaining ten recordings consist of only ear-EEG measurements, though a few subjects were asked to repeat a recording. Only the accepted recordings can be found in the BIDS formatted data set.

Each file consists of a video sequence followed by a sleep sequence. After the video sequence, the subject sent triggers to distinguish between the two sequences. Due to potential variability in triggering the device, the sequences remain in one file though it should be possible to manually sort the file into distinct video and sleep sequences.
There are no events.tsv files for Ear-EEG.

**Task description**

The patient performed tasks prior to going to bed. These recordings are labeled with 'video' as task. After his, the real recording started, which took place during the night and began when the subject went to bed. These recordings are labeled as having task 'sleep'.
For the first two recordings, the recording equipment was mounted in the afternoon. For the remaining recordings, the subject mounted the ear-EEG equipment by themselves immediately prior to going to bed. All recordings took place at the subject's home.

As can be seen in the diaries accompanying the recordings, the subjects wrote down recording start, electrode test start, when they went to bed, lights-out and recording end, and marked these in the data files using the trigger button on the equipment.

**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.

**2023年耳脑电（ear-EEG）睡眠监测（EESM23）数据集**

**概述**
本数据集依托2020-2022年开展的一项耳脑电睡眠监测研究项目采集得到。
数据集包含10名健康受试者的夜间脑电记录。其中前两次记录同时包含多导睡眠图（polysomnography, PSG）与耳脑电测量数据；剩余十次记录仅包含耳脑电测量数据，部分受试者曾重复参与记录。本数据集仅收录符合要求的记录文件，且采用脑成像数据结构（Brain Imaging Data Structure, BIDS）格式进行组织。
每份文件均包含一段视频序列与一段睡眠序列，视频序列结束后，受试者会发送触发信号以区分两类序列。由于设备触发可能存在潜在差异，两类序列仍保留在同一文件中，但可通过手动操作将其分离为独立的视频与睡眠序列。耳脑电数据未配套events.tsv文件。

**任务说明**
受试者在睡前完成了任务相关操作，这类记录被标记为"video"任务。在此之后，夜间睡眠记录正式启动，记录始于受试者上床就寝之时，这类记录被标记为"sleep"任务。
前两次记录的设备于下午完成安装；其余记录的耳脑电设备均由受试者在临睡前自行完成安装。所有记录均在受试者家中完成。
如配套的记录日志所示，受试者会记录记录启动、电极测试启动、上床就寝、熄灯及记录结束的时间节点，并通过设备上的触发按钮在数据文件中标记上述节点。

**数据格式**
本数据集遵循脑成像数据结构（BIDS）格式规范，具体使用的BIDS版本可参考dataset_description.json文件。脑电数据采用EEGLAB的".set"格式进行存储。
