Previous theories concerning the function of the corpus callosum have included a "topographic" column-to-column excitatory theory and a diffuse "regional" inhibitory theory. Here it is shown that a topographic inhibitory model, in conjunction with a postulate concerning surround inhibition among cortical columns, produces complementary patterns of cortical column firing which, although qualitatively different, do not imply quantitative metabolic asymmetries. The cognitive implications of such homotopic inhibition are discussed.
先前关于胼胝体功能的理论包括“地形学”的柱对柱兴奋性理论和弥散性的“区域”抑制性理论。本文表明，一种地形学抑制模型，结合关于皮质柱间周围抑制的假设，会产生皮质柱放电的互补模式，这些模式虽然在性质上不同，但并不意味着代谢上存在定量的不对称性。文中还讨论了这种同位抑制的认知意义。
