散粒噪声模型

Shot Noise Neuron Model

Zihao Xu

摘要:

在本文中,我们提出了一个基于散粒噪声的泄漏集成和发射神经元模型,并提供了一个详细的分析,这种模型的性能相比,传统的扩散近似模型。在理论神经科学中,有三种通用的神经元模型:房室神经元模型是一种基于电导的模型,它将生物神经元视为一个大电路。该模型的问题在于其结构的复杂性和自由参数的数量; Leaky集成和放电模型是一个更灵活的模型,由于特殊的设计称为阈值重置,其中神经元的电压达到阈值后被重置。该模型被提出作为房室模型的替代方案,以提供一个更符合生物学实际的模型,该模型可以捕获在实验中观察到的尖峰时间行为。除此之外,它的计算效率更高,因为它具有更少的自由参数;基于放电率的神经元模型使用神经元的放电率作为耦合神经元网络模型中的耦合项。这种模型可以很容易地在网络层面上进行分析。对该模型的理论分析证明了相变的存在,并表明在混沌区的计算能力得到了提高。

英文摘要:

In this paper, we propose a shot noise-based leaky integrated and firing neuron model and provide a detailed analysis of the performance of this model compared to the traditional diffusion approximated model. In theoretical neuroscience, there are three general neuron models in the field: Compartmental neuron model is a conductance-based model, in which it views the biological neurons as a large circuit. The problem of this model comes from its structural complexity and the number of its free parameters; Leaky integrated and firing model is a more flexible model due to the special design called threshold-resetting, in which the voltage of the neuron is reset after reaching the threshold. This model is proposed as an alternative to the compartment model to provide a more biologically realistic model that can capture spike timing behaviors that are observed in experiments. In addition to that, it is more computationally efficient since it has much less free parameters; Firing rate-based neuron model uses the firing rate of the neuron as the coupling terms in the coupled neuronal network models. Models of this kind can be easily analyzed on the network level. Theoretical analysis for this model proves the existence of phase transition and shows that the computational capacity is boosted in the chaotic regime.
