| 大多数神经场模型中的一个常见假设是网络是同质的和各向同性的,也就是说,权重分布取决于网络内交互种群之间的距离。然而,由于在皮层表层中发现的长程水平连接的斑块性质,真正的皮层更现实地被建模为各向异性和不均匀的二维介质(Bosking et al. 1997<ref>W H Bosking, Y Zhang, B Schofield and D Fitzpatrick. Orientation selectivity and the arrangement of horizontal connections in tree shrew striate cortex. J. Neurosci., 17:2112-2127, 1997.</ref>)。重量分布的各向异性可能导致不同方向的波速变化,而不均匀性可能导致随时间变化的波剖面,并可能导致波传播失败(Bressloff 2001<ref>P C Bressloff. Traveling fronts and wave propagation failure in an inhomogeneous neural network. Physica D, 155:83-100, 2001.</ref>)。 | | 大多数神经场模型中的一个常见假设是网络是同质的和各向同性的,也就是说,权重分布取决于网络内交互种群之间的距离。然而,由于在皮层表层中发现的长程水平连接的斑块性质,真正的皮层更现实地被建模为各向异性和不均匀的二维介质(Bosking et al. 1997<ref>W H Bosking, Y Zhang, B Schofield and D Fitzpatrick.
