论文摘要

神经刺激技术已经看到神经科学的兴趣激增,并控制了社区,因为它们具有可靠的治疗诸如帕金森氏病和抑郁症等疾病的潜力。所提供的刺激可以具有不同类型的刺激,例如电气和光遗传学,通常应用于大脑的特定区域,以将局部和/或全局动力学推向所需的(IN)活性的状态。但是,仍然缺乏对神经刺激功效的基本理论理解。从控制理论的角度来看,重要的是要了解每种刺激方式如何与复杂的大脑网络相互作用,以评估系统的可控性并开发具有神经生理学相关的计算模型,这些计算模型可用于以封闭环的方式设计刺激曲线。在本文中,我们回顾了(i)深脑刺激,(ii)经颅磁刺激,(iii)直流电流刺激,(iv)经颅电刺激,(v)光遗传学是研究和临床环境中最流行的五种神经刺激技术。对于每种技术,我们将综述的研究分为(a)理论驱动的生物物理模型,以捕获刺激源和神经元组织之间相互作用的低水平物理学,((b)数据驱动的刺激响应模型,这些模型捕获了刺激对兴趣的各种生物标志物以及(c)对数据驱动的动态动态的刺激效果的终端到端的终端效果。尽管由于其在控制设计方面的更大效用,我们的重点尤其是后者类别,但我们将主要的两个类别的关键作品视为发展动态系统模型的基础和环境。

Neurostimulation technologies have seen a recent surge in interest from the neuroscience and controls communities alike due to their proven potential to treat conditions such as Parkinson's Disease, and depression. The provided stimulation can be of different types, such as electric, and optogenetic, and is generally applied to a specific region of the brain in order to drive the local and/or global dynamics to a desired state of (in)activity. However, an underlying theoretical understanding of the efficacy of neurostimulation is still lacking. From a control-theoretic perspective, it is important to understand how each stimulus modality interacts with the complex brain network in order to assess the controllability of the system and develop neurophysiologically relevant computational models that can be used to design the stimulation profile in a closed-loop manner. In this paper, we review the computational modeling studies of (i) deep brain stimulation, (ii) transcranial magnetic stimulation, (iii) direct current stimulation, (iv) transcranial electrical stimulation, and (v) optogenetics as five of the most popular neurostimulation technologies in research and clinical settings. For each technology, we split the reviewed studies into (a)theory-driven biophysical models capturing the low-level physics of the interactions between the stimulation source and neuronal tissue, (b) data-driven stimulus-response models which capture the end-to-end effects of stimulation on various biomarkers of interest and (c) data-driven dynamical system models that extract the precise dynamics of the brain's response to neurostimulation from neural data. While our focus is particularly on the latter category due to their greater utility in control design, we review key works in the former two categories as the basis and context in which dynamical system models have been and will be developed.
