Localization accuracy for eccentricity mapping.

Ring eccentricity (chance level)	MNE	Beamformer (evoked response)	MSP
ECC 1 (33%)	40.5 (±31.6)	74.5 (±31.7)	38.4 (±37.7)
ECC 2 (33%)	40.1 (±41.1)	54.2 (±34.6)	24.6 (±26.5)
ECC 3 (33%)	76.9 (±25.2)	34.3 (±24.4)	33.0 (±24.4)
Mean	52.5	54.3	32.0

Percentage of active vertices that localized into the fMRI-defined subregion of individuals' retinotopic maps across early visual areas V1, V2, and V3, for ring stimuli. Results, averaged across stimuli and participants (±SD), are shown for MNE, beamformer, and MSP reconstruction methods.
