To investigate whether there is significant variability between the two scanners used in the present study, we examined the interhemispheric connectivity measures among controls in a between scanner fashion. Nine controls were scanned using the GE magnet and 7 using the Siemens magnet. The results of two-sample independent t-tests showed all three interhemispheric connectivity measures were similar across scanner (p > 0.05), suggesting the data from the two scanners are comparable.
