Main neurophysiological findings reported by fMRI studies of functional brain connectivity after SCI.

References	Main reported findings	Injury phase	Injury outcome
Hou et al. (2014a)	-↓ inter-hemispheric FC between bilateral M1 areas - ↑ intra-hemisperic FC between M1, PMC, SMA, TH and CB o between M1, SMA and CB: correlated(+) with impairment	subacute	incomplete
Hou et al. (2016)	- poor recovery: ↓ FC between o bilateral SMAs o right M1 and right SMA and PMC	subacute	incomplete
	- good recovery: ↑ FC between o bilateral SMAs o right M1 and right SMA and PMC o left M1 and right SMA
Min et al. (2015a)	-↑ FC between S1, SMA and BG -FC between S1 and S2	subacute	incomplete
Min et al. (2015b)	-characteristic path length consistently ↑ in SCI -no other significant differences in graph analysis between SCI and Healthy	subacute	incomplete
Oni-Orisan et al. (2016)	-overall ↓ FC -↓ FC between M1 and S1 and other nodes (intra- and inter-hemispheric) -↑ FC between left S1 and bilateral TH	chronic	complete
Kaushal et al. (2017a)	-overall ↓ FC whole brain subnetwork -FC midline sensorimotor network and left CB	chronic	complete
Kaushal et al. (2017b)	-↑ network modularity -local efficiency -no difference in global efficiency	chronic	complete
