An EEG dataset for interictal epileptiform discharge with spatial distribution information

This dataset contains annotated interictal epileptiform discharge (IED) from 84 patients (Peking Union Medical College Hospital, China), each contributing 20 minutes of continuous raw EEG recordings, using MAT format. The IEDs are categorized into five types based on occurrence regions. The states of consciousness (wake/sleep) are annotated.
<br>
Note on version 2:
The dataset has been updated. Specifically, a total of 37 annotations (31 deletions and 6 updates) were adjusted to ensure accuracy and consistency for analysis. These annotations were modified due to their atypical characteristics, differing from conventional interictal epileptiform discharges (IEDs). This refined dataset represents the final version used for training and validation in our associated paper entitled “An EEG dataset for interictal epileptiform discharges with spatial distribution information”.

本数据集包含来自中国北京协和医院84例患者的标注版发作间期癫痫样放电（interictal epileptiform discharge, IED）数据，每位患者提供20分钟连续原始脑电（electroencephalogram, EEG）记录，数据格式为MAT。发作间期癫痫样放电依据发作区域被划分为5类，同时标注了意识状态（清醒/睡眠）。
<br>
版本2说明：
本数据集已完成更新。为确保分析所需的标注准确性与一致性，共调整了37条标注（其中31条为删除操作，6条为更新操作）。这些被修改的标注因具有非典型特征，与常规发作间期癫痫样放电存在差异。本经过优化的数据集即为关联论文《An EEG dataset for interictal epileptiform discharges with spatial distribution information》中用于模型训练与验证的最终版本。
