Localization accuracy for angular mapping.

| V1 (25%) | 66.4 (±20.8) | 52.3 (±39.6) | 68.6 (±33.6) | 48.7 (±29.9) |
| V2 (25%) | 75.5 (±29.1) | 73.5 (±36.3) | 68.2 (±39.9) | 57.2 (±32.5) |
| V3 (25%) | 91.7 (±24.2) | 81.6 (±33.5) | 61.3 (±44.3) | 58.9 (±39.1) |
| mean (V1, V2, V3) | 77.9 | 69.1 | 66.0 | 54.9 |
| V3A (50%) | 100.0 (±0) | 97.4 (±8.6) | 83.2 (±36.2) | 64.9 (±34.8) |
Percentage of active vertices that localized to the fMRI-defined subregion of individuals' retinotopic maps for each early visual area, for quadrant stimuli. Results, averaged across stimuli and participants (±SD), are shown for MNE, beamformer (evoked and time-frequency approaches) and MSP reconstruction methods.
