Cortical structure and function are closely linked, shaping the neural basis of human behavior. This study explores how cortical surface area (SA), a structural feature, influences computational properties in human visual perception. Using a combination of psychophysical, neuroimaging, and computational modeling approaches, we find that variations in SA across the parietal and frontal cortices are linked to distinct behavioral patterns in a motion perception task. These differences in behavior correspond to specific parameters within a divisive normalization model, indicating a unique contribution of SA to the spatial organization of cortical circuitry. This work highlights the importance of cortical architecture in modifying computational processes that underlie perception, enhancing our understanding of how structural differences can influence neural function and behavior.
皮质结构与功能紧密相连，塑造了人类行为的神经基础。本研究探讨了作为一种结构特征的皮质表面积（SA）如何影响人类视觉感知中的计算特性。通过结合心理物理学、神经影像学和计算建模方法，我们发现顶叶和额叶皮质的SA变化与运动感知任务中的不同行为模式相关。这些行为差异对应于归一化除法模型中的特定参数，表明SA对皮质回路的空间组织有独特贡献。这项工作突出了皮质结构在修改感知基础的计算过程中的重要性，增进了我们对结构差异如何影响神经功能和行为的理解。
