我们为先前在个体受试者中映射的一组18个视网膜定位区域生成了概率区域图和最大概率图（MPM）（Georgieva等人，2009和Kolster等人，2010）使用四种不同的受试者间配准方法。使用最近开发的多峰表面匹配方法获得了最好的结果。最好的一组MPM在视觉区域之间具有相对平滑的边界，并且组平均区域大小与个体受试者的典型大小相匹配。视网膜定位区域和估计的皮质髓鞘含量的图之间的比较揭示了以下对应关系：（i）区域V1、V2和V3是重度髓鞘化的;（ii）MT簇是重度髓鞘化的，在MT/pMSTv边界附近具有峰值;（iii）背侧髓鞘密度峰值对应于区域V3D;（iv）phPIT簇是轻度髓鞘化的;和（v）髓鞘密度在V3A复合体的四个区域中不同。retinotopic MPM与cytoarchitectonic领域的比较，包括那些以前映射到fs_LR皮质表面图谱，揭示了区域V1 - 3和hOc1 - 3之间的对应关系，分别，但很少超出V3对应。这些结果表明，建筑和retinotopic面积边界是在某些地区的协议，和retinotopy提供了一个更细粒度的parcellation在其他地区。来自该分析的图谱数据集可免费作为其他研究的资源，这些研究将受益于人类视觉皮层中的视网膜定位和髓鞘密度图地标。生成了18个视网膜区域的最大概率图。多模态表面匹配被用来与髓鞘和细胞结构图进行比较。早期区域V1 - 3区域是重度髓鞘化的，V3D和大部分区域MT/pMSTv也是如此。与其他视网膜定位区域相比，phPIT簇是轻度髓鞘化的。早期区域V1 - 3对应于区域hOC 1 - 3，在V3之外几乎没有对应。
We generated probabilistic area maps and maximum probability maps (MPMs) for a set of 18 retinotopic areas previously mapped in individual subjects (Georgieva et al., 2009 and Kolster et al., 2010) using four different inter-subject registration methods. The best results were obtained using a recently developed multimodal surface matching method. The best set of MPMs had relatively smooth borders between visual areas and group average area sizes that matched the typical size in individual subjects. Comparisons between retinotopic areas and maps of estimated cortical myelin content revealed the following correspondences: (i) areas V1, V2, and V3 are heavily myelinated; (ii) the MT cluster is heavily myelinated, with a peak near the MT/pMSTv border; (iii) a dorsal myelin density peak corresponds to area V3D; (iv) the phPIT cluster is lightly myelinated; and (v) myelin density differs across the four areas of the V3A complex. Comparison of the retinotopic MPM with cytoarchitectonic areas, including those previously mapped to the fs_LR cortical surface atlas, revealed a correspondence between areas V1–3 and hOc1–3, respectively, but little correspondence beyond V3. 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. Maximum probability maps for 18 retinotopic areas were generated. Multimodal surface matching was used to compare with myelin and cytoarchitectonic maps. Early areas V1–3 areas are heavily myelinated, as are V3D and most of areas MT/pMSTv. The phPIT cluster is lightly myelinated compared to other retinotopic areas. Early areas V1–3 correspond to areas hOc1–3, with little correspondence beyond V3.
