The upper section (panels A–C) shows the fractional anisotropy (FA) in the tract between LGN and V1. A shows the FA along the length of the tract from LGN to V1 for control participants (red: left hemisphere, blue: right hemisphere), patients with unilateral V1 damage (red: lesion hemisphere, blue: intact hemisphere) and SBR (red: left hemisphere, green: right hemisphere). B is the average FA across the whole tract for each group and hemisphere. C shows the average FA in the distal portion of the tract (nodes 85–100). The asterisk indicates that SBR's FA values are ≥ 2 sd. below the mean control value.
