相关神经元群体信息编码的几何学

The Geometry of Information Coding in Correlated Neural Populations

Rava Azeredo da Silveira, Fred Rieke

摘要:

大脑中的神经元在它们的集体活动中代表信息。这种神经元群体代码的保真度取决于一个神经元的响应的可变性是否以及如何与其他神经元共享。二十年的研究已经调查了这些噪声相关性对神经编码特性的影响。我们提供了一个关于这个主题的理论发展的概述。使用简单的,定性的和一般的参数,我们讨论,分类,并与各种已发表的结果。我们强调噪声相关的精细结构的相关性,我们提出了一个新的方法来解决这个问题。在整个过程中,我们强调噪声相关性如何影响神经代码的几何图像。

英文摘要:

Neurons in the brain represent information in their collective activity. The fidelity of this neural population code depends on whether and how variability in the response of one neuron is shared with other neurons. Two decades of studies have investigated the influence of these noise correlations on the properties of neural coding. We provide an overview of the theoretical developments on the topic. Using simple, qualitative and general arguments, we discuss, categorize, and relate the various published results. We emphasize the relevance of the fine structure of noise correlation, and we present a new approach to the issue. Throughout we emphasize a geometrical picture of how noise correlations impact the neural code.
