Errors by visual area for dataset D10°.

aErrors are calculated in a typical leave-one-out fashion in which each subject is compared to the prediction found using all other subjects; all significant vertices between 1.25° and 8.75° of eccentricity are included, and the reported errors represent the median of all vertices from all subjects.bMedian absolute leave-one-out error between expected and observed values of all vertices.cMedian signed leave-one-out error, expected value minus observed value, of all vertices.dMedian absolute leave-one-out error, as calculated by predicting the polar angle and eccentricity of the left-out subject from the confidence-weighted mean of all other subjects.eMedian absolute error between observed values and those predicted by the algebraic model of retinotopy prior to any registration.fMedian absolute error between observed values from two identical 20 minute scans.Vertices for which the F-statistic of the polar angle and eccentricity assignments were below 5 were discarded.
