somatomotor

Accession: #: ds006035
Description: Multi-subject, multi-modal (sMRI+MEG+EEG) neuroimaging dataset for median nerve stimulation and motor responses.
This dataset contains MRI (T1w), MEG, and EEG data for median nerve electrical stimuli delivered at the right wrist.
The task was to respond by lifting the left hand idex finger as quickly as possible after each right median nerve stimulus.

----

Three anatomical fiducials were digitized for aligning the MEG with the MRI:
1. nasion (lowest depression between the eyes);
2. left pre-auricular point;
3. right pre-auricular point.

The following triggers are included in the .fif files and are also used in the “value” column of the meg events .tsv files:

背景概述

somatomotor数据集是一个多被试、多模态神经影像数据集，包含5名参与者的结构磁共振成像（sMRI）、脑磁图（MEG）和脑电图（EEG）数据，专注于研究右侧腕部正中神经电刺激后的左手食指快速运动反应。数据集总大小为3.07GB，遵循BIDS标准组织，便于神经影像分析。
