大脑中的神经元被淹没在由同步突触电流产生的振荡细胞外电位中。这些振荡的动力学是神经生理活动的主要特征之一,在基础神经科学中被广泛研究并在应用中使用。然而,我们对脑电波结构的解释以及我们对其功能的理解取决于用于数据分析的数学和计算方法。波动动力学的振荡性质有利于傅立叶方法,该方法已经统治该领域数十年,目前构成了唯一系统地研究大脑节律的方法。在接下来的研究中,我们概述了一种分析局部场势(LFP)波的替代框架,并讨论了它发现的一组新结构:一组离散的频率调制振荡过程-脑波振荡及其瞬时频谱动力学。
Neurons in the brain are submerged into oscillating extracellular potential produced by synchronized synaptic currents. The dynamics of these oscillations is one of the principal characteristics of neurophysiological activity, broadly studied in basic neuroscience and used in applications. However, our interpretation of the brain waves' structure and hence our understanding of their functions depend on the mathematical and computational approaches used for data analysis. The oscillatory nature of the wave dynamics favors Fourier methods, which have dominated the field for several decades and currently constitute the only systematic approach to brain rhythms. In the following study, we outline an alternative framework for analyzing waves of local field potentials (LFPs) and discuss a set of new structures that it uncovers: a discrete set of frequency-modulated oscillatory processes—the brain wave oscillons and their transient spectral dynamics.
