Although early visual experience is essential for the proper development of visual cortex, Striem-Amit et al. show that the underlying connectivity structure of retinotopic mapping is retained even in congenitally blind individuals. This basic organisational principle emerges independently of visual input and persists despite lifelong experience-dependent plasticity.

Resting-State Retinotopic Organization in the Absence of Retinal Input and Visual Experience (2015, methodology): “Our results suggest that these cross-modal responses coexist with neural firing patterns that reflect persisting retinotopic organization (also see Striem-Amit et al., 2015).”
Local-Global Parcellation of the Human Cerebral Cortex From Intrinsic Functional Connectivity MRI (2017, background): “2016) exploited the fact that cortical regions representing the same visual field locations are anatomically (Cragg 1969; Zeki 1969; Van Essen and Zeki 1978; Maunsell and Van Essen 1983) and functionally (Yeo et al. 2011; Wang et al. 2012; Striem-Amit et al. 2015) connected.”
How Visual Is the Visual Cortex? Comparing Connectional and Functional Fingerprints between Congenitally Blind and Sighted Individuals (2015, background): “RSFC patterns of early visual cortex with other visual regions have been reported to be similar between groups (Burton et al., 2014; Striem-Amit et al., 2015), and the intriguing differences of RSFC patterns within the visual cortex and between early visual cortex and nonvisual regions warrant…”
