Metabolic time series variation in PwPD relative to healthy controls. Subject-level coefficients of variation from extracted metabolic time series in (a) regions with metabolic alterations in PwPD in the present cohort. Marked dots represent outliers with values > 1.5 times the inter-quartile distance. (b) shows a scatterplot relating regional coefficients of variation to cognitive performance measured by cognition z-scores. The subjects marked in rectanglular shape represent the subjects classified as MCI. All images are shown in neurological display. Abbreviations: HC = control subjects, PwPD = persons with Parkinson’s disease, SN = substantia nigra, OC = occipital cortex, AP = anterior putamen, MFC = mid frontal cortex, AG = angular gyrus, PP = posterior putamen, MC = motor cortex, VC = coefficient of variation.
