Tutorial data for Imaging in neuroscience: with a focus on MEG and EEG methods

MEG/EEG/MRI tutorial data for the PhD course Imaging in neuroscience: with a focus on MEG and EEG methods at Karolinska Institutet, Stockholm, Sweden. For more information, see: https://github.com/natmegsweden/meeg_course Data from a single subject. The participant received 160 tactile stimulation to all five fingers of the right hand at a rate of 0.3 Hz while watching a silent movie. Continuous HPI was measured for the duration of the recording. MEG was recorded with a Neuromag Triux MEG scanner with 102 magnetometers and 204 planar gradiometers at a sample rate of 1000Hz. Simultaneously recorded electroencephalography (EEG) with 128 channels. Electrocardiogram (ECG) or electrooculogram (EOG) was measured together with MEG to control for artefacts from heartbeats and eye-blinks. Structural MRI.本数据集为瑞典斯德哥尔摩卡罗林斯卡学院神经科学成像博士课程的配套教学数据集，重点围绕脑磁图（Magnetoencephalography, MEG）与脑电图（Electroencephalography, EEG）研究方法展开。更多相关信息请参阅：https://github.com/natmegsweden/meeg_course。本数据集仅包含单一名受试者的实验数据：受试者在观看无声电影时，以0.3Hz的刺激频率对其右手五指共施加160次触觉刺激。整个记录过程中均同步采集连续头部位置指示器（Head Position Indicator, HPI）数据。脑磁图（MEG）采用搭载102台磁强计与204台平面梯度计的Neuromag Triux型脑磁扫描仪进行采集，采样率为1000Hz。同时同步采集128通道的脑电图（EEG）。为校正心跳与眨眼带来的生理伪迹，同步记录了心电图（Electrocardiogram, ECG）与眼电图（Electrooculogram, EOG）。此外还包含结构磁共振成像（Structural MRI）数据。
