Variance tests of the Euclidean distances of power distributions at rest and during movement.

Data are from the 16 contact-pairs with the highest relative power in each band from across the group. The total number of sides and patients from which these are drawn are also given. Theta, alpha, low beta, high beta and gamma were taken as 4–8 Hz, 8–12 Hz, 13–20 Hz, 21–32 Hz, and 60–90 Hz during rest and 4–8 Hz, 8–12 Hz, 16–20 Hz, 21–36 Hz and 59–73 Hz during movement, respectively. P-values in bold are significant following correction for multiple comparisons using the false discovery rate, and, when interpreted in terms of the difference in the subgroup mean Euclidean distance relative to that of the whole group (4.0 ± 1.9 mm), determine whether subgroups were more, or less, distributed in space than the master group of all 48 contacts.
