All P‐values for patients with PD are determined by a multilevel model, comparing all rest and stimulus epochs of patients with PD. All P‐values for group × condition interactions are determined by a multilevel statistical model, comparing the difference between all rest and stimulus epochs of control subjects with the difference between all rest and stimulus epochs of patients with PD. Analysis of regional changes was performed to explore the distribution of the odor‐induced changes within a frequency band. After Holm‐Bonferroni correction for multiple comparisons, regional P‐values lost significance.
