视觉系统的分层组织保留了拓扑结构，这在BOLD fMRI记录的“原始”人类视网膜定位图中经常丢失。在这里，我们提出了从人类视网膜切除功能磁共振成像数据生成拓扑保留和平滑视网膜切除图的方案。我们描述了数据预处理、3D表面平坦化和感兴趣区域（ROI）的选择，然后在ROI内平滑视网膜定位图。该方法可同时应用于视觉皮质区V1、V2和V3。有关使用和执行本协议的完整详情，请参阅。生成拓扑和平滑视网膜图的协议使用Beltrami系数来量化拓扑条件拓扑平滑通过约束优化实现该协议可同时应用于V1， V2和V3视网膜图出版商注：开展任何实验协议都需要遵守当地机构的实验室安全和伦理指导方针。视觉系统的分层组织保留了拓扑结构，这在BOLD fMRI记录的“原始”人类视网膜定位图中经常丢失。在这里，我们提出了从人类视网膜切除功能磁共振成像数据生成拓扑保留和平滑视网膜切除图的方案。我们描述了数据预处理、3D表面平坦化和感兴趣区域（ROI）的选择，然后在ROI内平滑视网膜定位图。该方法可同时应用于视觉皮质区V1、V2和V3。
The hierarchical organization of the visual system preserves topology, which is often lost in the “raw” human retinotopic maps derived from BOLD fMRI recordings. Here, we present the protocol for generating topology-preserving and smooth retinotopic maps from human retinotopy fMRI data. We describe data pre-processing, 3D surface flattening, and selection of the region of interest (ROI), followed by smoothing of the retinotopic maps within the ROI. This approach can be applied to visual cortical areas V1, V2, and V3 simultaneously. For complete details on the use and execution of this protocol, please refer to. A protocol for generating topological and smooth retinotopic maps The Beltrami coefficient is used to quantify the topological condition Topological smoothing is achieved through constrained optimization The protocol can be applied to V1, V2, and V3 retinotopic maps simultaneously Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
