Measurement datasets 1-3.01 for the “Kymata Atlas”

The electromagnetic measurements of the human cortex used in the creation of the Kymata Atlas (datasets 1-3.01). The recordings were made at the MRC Cognition and Brain Sciences Unit, using an Elekta Neuromag MEG (306 ch.) and an EasyCap EEG (70 ch.). Electromagnetic brain signals are recorded from participants as they experience passive, naturalistic, stimuli. The participants involved are asked to watch a movie and/or listen to the radio (without any further tasks asked of them) and the recordings are made during this period. Data is anonomised and averaged over participants. Due to millisecond differences in stimulus delivery, there are two sets of recordings, one syncronised to the sound stimulus, and one to the visual stimulus.本数据集为用于构建Kymata图谱（Kymata Atlas，数据集1-3.01）的人类大脑皮层电磁测量数据。数据采集工作于MRC认知与脑科学研究单元（MRC Cognition and Brain Sciences Unit）开展，采用Elekta Neuromag脑磁图（MEG，306通道）与EasyCap脑电图（EEG，70通道）设备完成记录。实验过程中，受试者在被动接收自然化刺激的状态下被采集电磁脑信号：受试者仅需观看电影或收听广播，无需完成任何额外任务，数据采集全程同步进行于该沉浸式体验阶段。所有数据已完成匿名化处理，并基于受试者群体进行组平均整合。由于刺激呈现存在毫秒级时间偏差，本数据集包含两套记录结果：一套与听觉刺激同步对齐，另一套与视觉刺激同步对齐。
