Table 3.

Activation peak shifts in tumor location subgroups.

Tumor location	n	Ipsilesional hemisphere	Healthy hemisphere
		Mean ± SD	Mean ± SD
Frontal, parietal, and frontal-parietal lobes	29	1.41 ± 0.73	1.10 ± 0.54
Frontal-insular-temporal and temporal lobes	46	0.84 ± 0.38	0.90 ± 0.47

This table reports the activation peak shifts from first to second MEG scan, calculated using the Euclidian equation, in subgroups of patients according to their tumor location. Abbreviations: SD, standard deviation; n, number of patients.
