This is data from an fMRI experiment which tests a number of basic sensory and cognitive functions.

Full details of the task and methods can be found in our pre-print on BiorXiv.org; https://www.biorxiv.org/content/early/2017/12/14/233783

There are two variants of the experiment. Both contain visual, auditory, and motor trials but one version also includes eye-movement trials, and another includes working-memory trials. They are labelled 'eye-movement' and 'working_memory' accordingly.

Two identical scanning sessions were conducted on each of 15 subjects. This enabled calculation of reliability statistics (ICC) as well as standard activation analyses.

Unthresholded activation maps and ICC maps are available here: https://neurovault.org/collections/3264/

Stimulus code for the tasks was written in PsychoPy and is also available here: https://figshare.com/articles/fMRI_control_task_zip/5162065 (DOI:
384 10.6084/m9.figshare.5162065).

本数据集源自一项功能磁共振成像（fMRI）实验，该实验旨在测试多项基础感知与认知功能。

实验任务与研究方法的完整细节可参阅我们发布于BiorXiv.org的预印本：https://www.biorxiv.org/content/early/2017/12/14/233783。

本实验包含两种变体，二者均涵盖视觉、听觉与运动任务试次；其中一个版本额外包含眼动任务试次，另一版本则包含工作记忆任务试次，二者分别被命名为“眼动（eye-movement）”与“工作记忆（working_memory）”。

本研究共对15名受试者开展两次完全相同的扫描会话，这使得我们既能计算可靠性统计量——组内相关系数（ICC），也可开展标准激活分析。

本实验的刺激代码基于PsychoPy编写，同样可通过以下链接获取：https://figshare.com/articles/fMRI_control_task_zip/5162065（DOI: 10.6084/m9.figshare.5162065）。
