To establish whether the lower-1 α and γ band ERS/ERD significantly differed from zero a one-sample t-test was conducted. The t-test for the lower-1 α was significant for the MM (ERS) group (t(11) = 4.54; p < .002; M = −13.86; SD = 10.57), and the BM group (ERD) (t (11) = 2.63; p < .023; M = 13.87; SD = 18.28). The t-test for the γ band was only significant for the BM group (t(11) = 3.80; p < .003; M = 15.15; SD = 13.83).
