The area of the foveal confluence is similar in both BCM carriers and normal controls.

<p>Flattened pseudo-color phase maps are used to visualize retinotopic maps for: a) JC_1041, b) JC_1044, c) JC_0120, and d) control. Expanding ring stimuli were used to map retinotopic eccentricity. White contours outline the foveal confluence (0°–2°) of early visual areas. Image pairs for each subject are left and right hemispheres. Gray background shows flat map of cortical anatomy. Dark regions are sulci; bright regions are gyri. Note that because the underlying anatomy is different for each subject and hemisphere, areas are not directly comparable between images; measurements are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057956#pone-0057956-t002" target="_blank">Table 2</a>.
