Dataset accompanying 'The Representation of Priors and Decisions in The Human Parietal Cortex'

This dataset accompanies the manuscript 'The Representation of Priors and Decisions in The Human Parietal Cortex', published in PLoS Biology. This dataset consists of: 1) Biophysical model simulations of a neural mass model performing a 2-alternative perceptual decision making task. 2) MEG data from 26 human volunteers performing the same task (see fig1 of the manuscript). MEG data were combined with anatomical MRI scans (not shared) to source localise brain activity in parietal cortex. The neural source time courses are shared. Full details can be found in the methods section of the manuscript. 3) Analysis code to reproduce all main data figures in the manuscript. Details of how to run the analyses are included in the analysis code documentation. 4) .txt files including the summary data necessary to reproduce figures in the manuscript. This is to allow users who do not have access to matlab to access the data underlying the figures without running the entire analysis pipeline.本数据集配套发表于《PLoS Biology》的学术论文《人类顶叶皮层中的先验表征与决策》（原英文标题：The Representation of Priors and Decisions in The Human Parietal Cortex）。本数据集包含以下内容：1）执行双择一知觉决策任务的神经群模型的生物物理模型仿真数据；2）26名执行相同任务的人类受试者的脑磁图（MEG，Magnetoencephalography）数据（详见论文图1）。该脑磁图数据已与未公开的解剖学磁共振成像（MRI，Magnetic Resonance Imaging）扫描结果结合，用于对顶叶皮层的脑活动进行源定位，本次公开的数据集为神经源时间序列数据，完整细节可参见该论文的方法部分；3）用于复现论文中所有主数据图的分析代码，代码的运行说明已包含在分析代码文档中；4）包含复现论文图表所需汇总数据的纯文本（.txt）文件，以供无法使用Matlab的用户无需运行完整分析流程，即可获取图表背后的核心数据。
