Abstract
A new nonlinear dynamical analysis is applied to complex behavior from neuronal systems. The conceptual foundation of this analysis is the abstraction of observed neuronal activities into a dynamical landscape characterized by a hierarchy of "unstable periodic orbits" (UPOs). UPOs are rigorously identified in data sets representative of three different levels of organization in mammalian brain. An analysis based on UPOs affords a novel alternative method of decoding, predicting, and controlling these neuronal systems.
摘要
一种新的非线性动力学分析方法被应用于神经元系统的复杂行为。该分析的概念基础是将观察到的神经元活动抽象为一个由“不稳定周期轨道”（UPOs）层次结构所表征的动力学格局。在代表哺乳动物大脑三个不同组织层次的数据集里，严格识别出了UPOs。基于UPOs的分析为解码、预测和控制这些神经元系统提供了一种全新的替代方法。
