MEG Data Representing a Gamma-Band Response during the Pain Empathy paradigm

The data contains 88 matrices from 44 participants, with 2 matrices for each participant. Each matrix represents either the pain ('p') or the no-pain ('n') conditions. In each matrix you will find 4 dimensions: trials * MEG-sensors * spectral-frequency (80:10:150) * time本数据集涵盖44名受试者的88个矩阵，每名受试者对应2个矩阵，分别对应疼痛（'p'）与无疼痛（'n'）两种实验条件。每个矩阵均包含4个维度：试次（trials）×脑磁图（MEG）传感器×频谱频率（spectral-frequency，80:10:150，即80Hz起始、步长10Hz至150Hz）×时间（time）。
