Using the data of Hubel and Wiesel (1974) J. comp. Neurol. 158, 295-306, on macaque, the shape of the operculum of striate cortex (area 17) is calculated from their magnification factor values assuming that the cortical magnification factor is locally isotropic with respect to displacement on the cortical surface (from a fixed point of origin). Using geometric considerations, the shape predicted from the isotropic assumption is inconsistent with the actual shape given by anatomical reconstruction by LeVay, Hubel and Wiesel (1975) J. comp. Neurol. 159, 559-576. Rather the true shape is more consistent with the hypothesis that on the average the magnification factor along a meridian is twice the value as orthogonal to it. Except in the region of the horizontal meridian, this is often the same as assuming that the magnification factor across ocular dominance columns is twice that going parallel to them.
利用休伯尔和威塞尔（1974年，《比较神经学杂志》第158卷，第295 - 306页）关于猕猴的数据，假设皮质放大因子相对于皮质表面上的位移（从一个固定的原点开始）在局部是各向同性的，从他们的放大因子值计算出纹状皮质（17区）的盖的形状。通过几何考虑，从各向同性假设预测的形状与勒维、休伯尔和威塞尔（1975年，《比较神经学杂志》第159卷，第559 - 576页）通过解剖重建给出的实际形状不一致。相反，真实形状更符合这样的假设，即平均而言，沿着子午线的放大因子是与其正交方向上值的两倍。除了水平子午线区域，这通常与假设穿过眼优势柱的放大因子是与其平行方向上放大因子的两倍相同。
