Table 2.

Mean theta peak power values, standard errors, and confidence intervals for pre/post and stimulation conditions (in-phase/anti-phase/sham).

				95% Confidence interval
Condition	Stimulation	Mean	SE	Lower bound	Upper bound
Pre	In-phase	1.67	0.30	1.04	2.31
	Anti-phase	1.63	0.29	1.02	2.24
	Sham	1.90	0.39	1.08	2.71
Post	In-phase	1.83	0.33	1.14	2.52
	Anti-phase	1.76	0.31	1.10	2.42
	Sham	1.83	0.36	1.08	2.58

EEG electrodes in immediate vicinity of stimulation electrodes, i.e., Fz, F8, Pz, P8, Oz were used in order to compute mean peak power values.
