Cortical thinning in iRBD map onto specific regional tracer density, resting-state networks, and cytoarchitectonic classes. (A) Brain renderings and scatterplots showing the tracer density maps of the receptors, transporters, and binding sites associated with cortical thickness W-scores in iRBD. The violin plots show the empirical correlations tested against distributions of correlations from sets of spatial and random null models. The asterisk indicates the significant associations after Bonferroni correction. Radar charts showing the correlation between cortical thickness W-scores in iRBD and (B) resting-state networks and (C) cytoarchitectonic classes. The regular line represents the empirical correlations, and the dashed line represents the average correlation observed in sets of 10 000 spatial null models. The asterisk indicates the networks and classes where the observed spatial correlation was significantly different from the null correlation.
