在本文中,提出了一种用于对轴突引导进行建模的仿真工具。一个可以实现多种模型的数学框架与高效的数值算法一起被开发出来。在我们的框架中,可以定义由引导分子的浓度场与有限维状态向量相结合组成的模型。这些载体可以表征迁移的生长锥、释放引导分子的目标神经元或充当膜结合或可扩散引导分子来源的其他细胞。介绍了基本的数学框架以及解决这些问题的数值方法。我们的模拟工具的潜在应用通过许多示例来说明,包括地形测绘模型。
In this paper, a simulation tool for modeling axon guidance is presented. A mathematical framework in which a wide range of models can been implemented has been developed together with efficient numerical algorithms. In our framework, models can be defined that consist of concentration fields of guidance molecules in combination with finite-dimensional state vectors. These vectors can characterize migrating growth cones, target neurons that release guidance molecules, or other cells that act as sources of membrane-bound or diffusible guidance molecules. The underlying mathematical framework is presented as well as the numerical methods to solve them. The potential applications of our simulation tool are illustrated with a number of examples, including a model of topographic mapping.
