我们提出了一种机制,使外观的边界细胞神经元发射的边界的导航外壳。该方法是基于最近发现的离散复分析的三角形格,它允许构建离散的复解析函数的缩影,并利用其固有的能力,以达到最大值的边界处的通用格域。事实证明,离散复杂框架的某些元素很容易出现在网格单元的振荡模型中。我们证明,这些模型可以进一步扩展,产生细胞,增加他们的活动对边界的导航环境。我们还构建了一个网络模型的神经元与边界绑定的发射,符合振荡模型。
We propose a mechanism enabling the appearance of border cells—neurons firing at the boundaries of the navigated enclosures. The approach is based on the recent discovery of discrete complex analysis on a triangular lattice, which allows constructing discrete epitomes of complex-analytic functions and making use of their inherent ability to attain maximal values at the boundaries of generic lattice domains. As it turns out, certain elements of the discrete-complex framework readily appear in the oscillatory models of grid cells. We demonstrate that these models can extend further, producing cells that increase their activity toward the frontiers of the navigated environments. We also construct a network model of neurons with border-bound firing that conforms with the oscillatory models.
