Localization accuracy for quarter-ring stimuli.
| MNE | Beamformer | |
|---|---|---|
| ANGULAR LOCALIZATION (CHANCE LEVEL 25%) | ||
| Upper field stimuli | 74.3 (±30.1) | 75.4(±29.3) |
| Lower field stimuli | 72.4 (±33.4) | 42.9 (±37.9) |
| Combined mean | 73.3 | 59.0 |
| ECCENTRICITY LOCALIZATION (CHANCE LEVEL 33%) | ||
| Upper field stimuli | 45.7 (±34.4) | 40.4 (±41.0) |
| Lower field stimuli | 56.8 (±33.5) | 58.2 (±40.5) |
| Combined mean | 51.4 | 49.0 |
Percentage of active vertices in early visual cortex that localized into the fMRI-defined subregion of individuals' retinotopic maps, for quarter-ring stimuli. Results are reported for upper or lower visual field and averaged across stimuli and participants (±SD) according to either angular (expected quadrant) or eccentricity retinotopy (expected eccentricity band).
