The mapped V1–V2 connectivity is reproducible across scans (scan–rescan) with the 32-channel and the flexible surface coils. (a) ICC matrix computed between the mean of the scan–rescan 32-channel coil connectivity and the flexible surface coil connectivity across six hemispheres shows mostly high correlation. (b) Percentage connectivity for all detected retinotopic and non-retinotopic fiber tracks using the 32-channel and flexible surface coils averaged over all subjects supports high reproducibility for the three experiments. (c) Corresponding fiber track geometries show high reproducibility across the scan–rescan and the flexible surface coil experiments as demonstrated for a representative subset of V1–V2 fiber tracks.
