Functional connectivity of the Precuneus reflects effectiveness of visual restitution training in chronic hemianopia.

•We found a visual restitution training effect modulated by attention in hemianopia.•When at rest, Precuneus and Occipital Pole Network are functionally connected.•The strength of this connection prior to training was positively related to training effect.•Precuneus may play a role in visual field improvements by modulating attention.•Our finding may help identifying patients most likely to benefit from training.
