Correspondences between retinotopic areas and myelin maps in human visual cortex.

Abdollahi RO, Kolster H, Glasser MF, Robinson EC, Coalson TS, Dierker D, Jenkinson M, Van Essen DC, Orban GA - Neuroimage (2014)

Bottom Line: The best results were obtained using a recently developed multimodal surface matching method.These results indicate that architectonic and retinotopic areal boundaries are in agreement in some regions, and that retinotopy provides a finer-grained parcellation in other regions.The atlas datasets from this analysis are freely available as a resource for other studies that will benefit from retinotopic and myelin density map landmarks in human visual cortex.

Probability atlases (color code see inset) and 8% (dark color), 50% (medium color) and 100% (light color) probability contours obtained with FreeSurfer registration (left columns) and MSM-retino registration (right columns) for three cortical areas: V1 (blue A–D), MT (brown-yellow, E–H) and pFST (green, I–L). Note that the 100% probability plateau is not continuous in V1, because of the cut in the flatmap along the calcarine sulcus used to generate the original patches in Freesurfer. Note also the presence of an outlier in the pFST maps.

Note also the presence of an outlier in the pFST maps.

Mentions: The probabilistic area map (PAM) of a given area reflects the degree of consistency in size, shape and location across subjects after registration to an atlas by a particular method. As shown in Fig. 3 for three exemplar areas (V1, MT, and pFST) the distribution of the PAM on the surface represents a two-dimensional step function with a central maximum or plateau surrounded by a progressive step-wise decline whose steepness depends on the residual variation in size, shape, and location of the area (Fig. 3, leftmost column for FreeSurfer registration and third column for MSM-retino registration). These PAMs were further characterized using the contours for maximum probability, 50% probability, and the minimum probability threshold (8%), which corresponds to the maximum possible extent of the PAM. These contours are shown in the second and fourth columns of Fig. 3 in increasingly dark shades of blue (V1, top row), orange (MT, middle row) and green (pFST, bottom row).
