AgeRisk
收藏资源简介：
BACKGROUND This dataset contains magnetic resonance imaging data (N=187) from a sample of healthy human participants between 16 and 81 years of age. The neuroimaging session was conducted as part of a cross-sectional study (AgeRisk) of the developmental trajectories of risk preference, impulsivity, and self-control. The neuroimaging session was conducted as the last of three study sessions, and comprised a structural (T1w) scan, as well as functional scans during completion of the Balloon Analogue Risk Task (2 runs) and a delay discounting paradigm. Due to time constraints, the delay discounting task was completed by 178 out of 187 participants. This dataset was collected between 2016 and 2017 at the University Hospital Basel, Switzerland. The dataset was skull stripped prior to uploading using the FSL Brain Extraction Tool.

背景 本数据集包含187名健康人类受试者的磁共振成像（magnetic resonance imaging, MRI）数据，受试者年龄介于16至81岁之间。本次神经影像扫描作为一项关于风险偏好、冲动性与自我控制发展轨迹的横断面研究（AgeRisk）的组成部分开展。神经影像扫描为三项研究环节中的最后一项，包含结构（T1加权，T1w）扫描，以及完成气球模拟风险任务（Balloon Analogue Risk Task）和延迟折扣范式时采集的功能扫描数据，其中气球模拟风险任务包含2个扫描序列。受时间限制，187名受试者中仅有178人完成了延迟折扣任务。本数据集于2016至2017年间在瑞士巴塞尔大学医院采集。上传数据集前，已使用FSL脑提取工具（FSL Brain Extraction Tool）对数据进行了去颅骨预处理。如需了解受试者样本、研究设计与实验材料的详细信息，请查阅JSON附属文件及下文所列参考文献。 参考文献 1.
