Distribution of the AME positions during the recording session. Each red dot corresponds to the median position of the AME relative to the center of the visual stimulus display during the recording of an fMRI volume (duration of 1940 ms). This accounts for saccadic eye movements as well as drifts. The variability of the eye positions was measured as the area of the 95% confidence ellipses (black). A, B, AME positions of subject A1 (A) and A2 (B) during their two fMRI sessions. C, Lack of correlation between the 95% confidence ellipse areas (in the abscissas) and the pRF sizes (FFE, blue; AME, red). Each dot corresponds to an amblyopic participant, the colored dotted lines being the regression lines. D, Lack of correlation between the squint angles and the pRF sizes from the AME. Each dot corresponds to an amblyopic participant, the colored dotted line being the regression line.
