ANT: Healthy aging and Parkinson's disease

This project contains 46 healthy aging (n = 25, RC41\*) participants and
participants with Parkinson's disease (n = 21, RC42\*) at two sessions each. At
each session, subjects acquired 6 repetitions of the ANT task (1-6). ANT task
scans are the same by number across subjects, although they were presented in
varying orders. Task timing, anatomical scans, resting scans, and DTI scans
by session are also included.

The `derivatives/` directory contains AFNI-preprocessed scans as well as
anatomical scans skullstripped before defacing. The derivatives have been
slice-timing corrected already, so 0s are provided for that field.

At the top level is complete demographic information and the AFNI script for
preprocessing.

Exceptions
----------
One subject (RC4206) had an acquisition error during their second session
structural scan. Correspondingly, their structural scan from their first
session has been copied for their second session to create a valid
BIDS directory.

DTI scans are not present for four subjects for the first session (RC4106, RC4204,
RC4205, RC4226) and three subjects for the second session (RC4103, RC4106, RC4205).

DTI scans for the first session of two participants have a larger dimension
size compared to other DTI scans (RC4101, RC4201).

背景概述

该数据集是一个神经影像数据集，专注于健康老年人和帕金森病患者的对比研究，包含46名参与者（25名健康老年人，21名帕金森病患者），每个参与者有两个会话。数据集提供MRI数据，包括ANT任务、静息态、解剖扫描和DTI扫描，并附有预处理衍生数据和人口统计信息，适用于研究注意力网络和疾病相关脑功能变化。
