Demonstration of the hemispheric shift of activation over time

Time window	E1	E2	E3	E4	E5
Sum of significant pseudo‐t values right hemisphere	−2.6494	0	0	−55.1507	−9.4685
Sum of significant pseudo‐t values left hemisphere	−5.8861	−1.9097	−18.8312	−50.7963	−3.2234
Lateralization index of pseudo‐t activation	0.3792	1	1	−0.0411	−0.4921

The group results of cumulative significant pseudo‐t activation are shown for all five time intervals and in both hemispheres. The first three time windows (E1–E3) reveal left hemispheric lateralization. In E2 and E3 even no significant ERD was found in the right hemisphere. This results in a lateralization index of 1. The time interval E4 shows bilateral activation with slight right hemispheric lateralization that accelerates in the last observed time interval (E5).
