a Distribution of peak frequencies in all brain regions of all individuals from the different groups. b Distribution of frequency peaks in alpha and beta bands. The colour inside the dots is the difference (PD-OFF - HC ses1) of the mean peak frequency of each brain region in alpha (left) and beta (right). The edge colour of the dots is the normalised difference (PD-OFF - HC ses1) of proportion of individuals having at least one peak frequency in the given band. c, d Distribution of frequency peaks in theta (c) and gamma (d) bands. Dot colour indicates mean peak frequency within the band. Edge colour of the dots indicate the proportion of individuals having such peaks in the given group.
