Chinese Color Nest Project - Healthy Elderly in China

The dataset contains a total of 368 scans with 205 healthy elderly volunteers from China. 163 of them were scanned for twice. All volunteers were recruited through methods such as WeChat moments, poster advertising, and word of mouth. Data collection was conducted at the 3T scanner (GE MR 750) of the Magnetic Resonance Research Center at the Institute of Psychology, Chinese Academy of Sciences. The multimodal imaging protocol included a set of high-resolution T1-weighted structural images, T2-weighted structural images, resting-state functional images, and task-state functional MRI sequences. Behavioral data included tests such as word list recall, attention cancellation, number-symbol, and Wechsler Block Design. The dataset is divided into three parts: The first part includes 42 elderly volunteers, with 19 females and 23 males; age range 55 to 78 years, average age = 65.07 ± 6.43 years. The second part is a gamified working memory training data set, including 63 participants, among which 57 had a posttest. 43 females and 20 males with age range 60 to 90 years were included in the second part. The third part is a gamified cognitive control training data set, including 100 participants, among which 93 had a posttest. 82 females and 18 males with age range 60 to 90 years were included in the third part.

本数据集共包含368例脑部扫描影像，招募自205名中国健康老年志愿者，其中163名志愿者接受了两次扫描。所有志愿者均通过微信朋友圈、海报宣传及口碑相传等方式招募。数据采集工作在中国科学院心理研究所磁共振成像研究中心的3T磁共振扫描仪（GE MR 750）上完成。
该数据集采用多模态成像协议，包含高分辨率T1加权结构像（T1-weighted structural images）、T2加权结构像（T2-weighted structural images）、静息态功能像（resting-state functional images）以及任务态功能磁共振成像序列。
行为学数据涵盖字词列表回忆、注意力划消、数字-符号匹配以及韦氏积木测验（Wechsler Block Design）等测试项目。
本数据集分为三个子部分：
第一部分包含42名老年志愿者，其中女性19名，男性23名；年龄跨度为55至78岁，平均年龄为65.07±6.43岁。
第二部分为游戏化工作记忆训练数据集，包含63名参与者，其中57名完成了后测；该部分志愿者年龄范围为60至90岁，女性43名，男性20名。
第三部分为游戏化认知控制训练数据集，包含100名参与者，其中93名完成了后测；该部分志愿者年龄范围为60至90岁，女性82名，男性18名。
