305-视觉与躯体图谱的拓扑对齐

这项研究开发了一种新颖的双源计算模型，旨在同时绘制人类大脑中躯体定位（触觉）和视野范围（视觉）的图谱。通过分析静息态数据，该模型成功揭示了经典的躯体感觉区域内固有的躯体定位组织结构。关键发现是，当参与者观看自然视频时，躯体定位的连接性显著增强，并扩展到通常被认为是纯粹视觉的背外侧视觉皮层。在这些区域内，视觉和躯体感觉的表征被发现是拓扑对齐的，揭示了一种跨模态的计算机制。这种对齐使得体感调整能够预测像素对视觉场位置或视觉身体部位类别的选择性。最终，研究提出这种视觉-体感图谱的桥接机制，是形成具身视觉体验以及支持动作、社会认知和语义处理的计算基础。References:* Hedger N, Naselaris T, Kay K, et al.
