Figure 2.

Visual field maps extracted from pRF positions of a normal subject and an amblyopic participant (threshold of variance explained set at 10% for illustration purpose only). The figure shows posteroinferior views of left and right inflated surfaces. A, B, Maps for polar-angle (left) and eccentricity (right) of a normal subject. A, Maps when the stimulus was seen with the DE only. B, Maps when the stimulus was seen with the nDE only. C, D, Maps for polar angle (left) and eccentricity (right) of an amblyopic subject (subject A8). C, Maps when the stimulus was seen with the FFE only. D, Maps when the stimulus was seen with the AME only. C, D, Global organization of the visual information coming from the AME is consistent. The main difference between the two eyes is that there are fewer voxels that survived thresholding for the AME. The delimitation of the visual areas was based on the position of the upper vertical meridian (UVM; solid black line), lower vertical meridian (LVM; dotted black line), and horizontal meridian (HM, solid white line). The two insets on the top show the color overlays indicating the visual field angle (left) and the eccentricity (right). The visual areas are labeled on the polar-angle maps on A and C. For orientation clarity, the major sulci (outlined in dotted white lines) are labeled on the eccentricity maps (A, C). IPS, Intraparietal sulcus; TOS, transverse occipital sulcus; AOS, anterior occipital sulcus; LOS, lateral occipital sulcus; CaS, calcarine sulcus; OTS, occipitotemporal sulcus; COS, colateral sulcus.
