Dataset Description
The present study utilized an openly available ANT fMRI dataset archived by OpenNeuro (Day et al. , 2019), which has been analyzed in two previous studies for other purposes (Madhyastha et al. , 2015; Boord et al. , 2017). The dataset belonged to a cohort study (Cholerton et al. , 2013) using the classical ANT fMRI task (Fan et al. , 2005) to study attention dysfunction in schizophrenia. Twenty-five participants with Parkinson’s disease (mean age: 66 years, ranging from 45 to 86 years) and twenty-one healthy aging participants (mean age: 62 years, ranging from 41 to 76 years) attended two fMRI sessions separated by 1 to 3 weeks. At each session, subjects completed six runs of the ANT task and scanned for a high-resolution anatomical image for spatial registration and normalization. Demographic information from this dataset has been reported in previous studies (Madhyastha et al. , 2015; Boordet al. , 2017). The associated project was approved by the University of Washington Institutional Review Board (#41304), and subjects provided written informed consent.
