Dataset of simultaneous scalp EEG and intracranial EEG recordings and human medial temporal lobe units during a verbal working memory task

We present an electrophysiological dataset recorded from nine subjects during a verbal working memory task. Subjects were epilepsy patients undergoing intracranial monitoring for localization of epileptic seizures. Subjects performed a modified Sternberg task in which the encoding of memory items, maintenance, and recall were temporally separated. The dataset includes simultaneously recorded scalp EEG with the 10-20 system, intracranial EEG (iEEG) recorded with depth electrodes, waveforms and spike times of 1526 units recorded in the medial temporal lobe, and the MNI coordinates and anatomical labels of all intracranial electrodes. Subject characteristics and information on sessions (set size, match/mismatch, correct/incorrect, response, response time for each trial) are also provided. This dataset enables the investigation of working memory by providing simultaneous scalp EEG and iEEG recordings, which can be used for connectivity analysis, alongside hard to obtain unit recordings from humans.

本研究发布一项电生理数据集，该数据集采集自9名受试者在言语工作记忆任务期间的实验数据。受试者均为需接受颅内监测以定位癫痫发作灶的癫痫患者。受试者完成改良版斯特恩伯格（Sternberg）任务，该任务将记忆项目编码、信息维持与回忆三个环节在时间维度上进行了分离。本数据集包含同步采集的采用国际10-20电极放置系统的头皮脑电图（scalp EEG）、通过深部电极采集的颅内脑电图（intracranial EEG, iEEG）、内侧颞叶中1526个单神经元单元的放电波形与尖峰时间，以及所有颅内电极的蒙特利尔神经学研究所（MNI）坐标与解剖学标签。此外，数据集还提供了受试者特征信息，以及各试验回合的相关参数：记忆集大小、匹配/非匹配状态、正确/错误反应、反应类型与每一试次的反应时。该数据集同步采集了头皮脑电图与颅内脑电图，可用于脑连接分析，同时包含了难以获取的人类神经元单元放电记录，为工作记忆相关研究提供了有力支撑。
