Significant differences in the FC of V1 between LB and SCs

Brain regions	BA	Peak t-scores	MNI coordinates (x, y, z)	Cluster size (voxels)
FC in left V1
Bilateral cuneus/lingual gyrus/calcarine	18/19/30	−5.567	9, −75, 6	1,280
Left precentral gyrus and postcentral gyrus	2/3/4	−4.183	−48, −24, 45	442
FC in right V1
Bilateral cuneus/lingual gyrus/calcarine	18/19/30	−5.503	−15, −72, 3	1,238
Left precentral gyrus and postcentral gyrus	2/3/4/6	−3.812	−60, −12, 33	422

Note: The statistical threshold was set at the voxel level with P<0.01 for multiple comparisons using Gaussian random-field theory (two-tailed, voxel-level: P<0.01, GRF correction, cluster-level: P<0.05).

Abbreviations: BA, Brodmann area; FC, function connectivity; GRF, Gaussian random field; LB, late blindness; MNI, Montreal Neurological Institute; SCs, sighted controls; V1, primary visual cortex.
