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.
