群体耦合理论及其在描述大群体交互神经元高阶关联中的应用

Theory of population coupling and applications to describe high order correlations in large populations of interacting neurons

Haiping Huang

摘要:

为了了解神经元群体中的集体尖峰活动,揭示负责这些紧急功能状态的基本电路变量是至关重要的。本文对最近在小鼠和猴的视觉皮层研究中提出的群体耦合的平均场理论进行了发展,将单个神经元的活动与群体活动联系起来,并将原来的形式扩展到二阶,将神经元对的活动与群体活动联系起来,以解释神经元数据中观察到的高阶相关性。我测试的蝾螈视网膜数据和行为大鼠的皮层尖峰数据的计算框架。对于视网膜数据,原始形式的群体耦合及其高级形式可以分别解释两细胞相关性和三细胞相关性的显著部分。对于皮层数据,性能变得更好,二阶种群耦合揭示了局部皮层回路中的非局部效应。

英文摘要:

To understand the collective spiking activity in neuronal populations, it is essential to reveal basic circuit variables responsible for these emergent functional states. Here, I develop a mean field theory for the population coupling recently proposed in the studies of visual cortex of mouse and monkey, relating the individual neuron activity to the population activity, and extend the original form to the second order, relating neuron-pair's activity to the population activity, to explain the high order correlations observed in the neural data. I test the computational framework on the salamander retinal data and the cortical spiking data of behaving rats. For the retinal data, the original form of population coupling and its advanced form can explain a significant fraction of two-cell correlations and three-cell correlations, respectively. For the cortical data, the performance becomes much better, and the second order population coupling reveals non-local effects in local cortical circuits.
