A model of the functional architecture in monkey striate cortex is proposed, based on recent data, in which the global structure is a result of the local structure. The local structure itself is organized around the cytochrome oxidase blobs. It is characterized by different anisotropic distributions of preferred orientations in upper and lower layers. In particular, the upper layers show a bias for "radial" orientations and the lower layers show a bias for "concentric" orientations (Bauer and Dow 1989). This organization may derive from the symmetry of the visual field and visual system which tends to be radial or concentric rather than cartesian. Functionally, the increased sensitivities of the different radial and concentric maps of orientation and movement detectors seem to be an adaptive fit to optic flow fields on the retina during complex movements of the subject in its environment.
基于近期数据，提出了一种猕猴纹状皮层功能架构模型，其中全局结构是局部结构的结果。局部结构本身围绕细胞色素氧化酶斑进行组织。其特征在于上层和下层中偏好方向的不同各向异性分布。具体而言，上层表现出对“径向”方向的偏好，而下层表现出对“同心”方向的偏好（鲍尔和道，1989年）。这种组织可能源于视野和视觉系统的对称性，其倾向于呈径向或同心状而非笛卡尔坐标状。在功能上，不同的径向和同心方向及运动检测器图谱的敏感性增加，似乎是在主体在其环境中进行复杂运动期间，对视网膜上的光流场的一种适应性匹配。
