Coordinates showing a significant positive association between homotopic functional connectivity and behavioral measures of mixing costs for long and short Cue-to-Target-Interval (CTI)

Behavioral measure	Region	Peak voxel coordinates			Peak MNI coordinates			Brodmann area	Cluster size (#voxels)	FWE p
		x	y	z	x	y	z
Mixing costs, Short CTI	Superior frontal gyrus	|30|	58	42	|4|	30	53	8	27	0.014
Mixing costs, Long CTI	Supramarginal gyrus	|14|	28	40	|46|	− 48	44	40	29	0.005

The location of significant clusters is referred to in terms of the coordinates of peak p value in the ICBM 2009a Nonlinear symmetric template voxel space (3 voxel size isotropic resolution; neurological orientation). Coordinates are reported also in MNI after registering the clusters in the 2 mm MNI template. Clusters are reported in the left hemisphere for simplicity but refer to homotopy measures computed between both hemispheres. pFWE p value after family-wise error correction
