论文摘要
星形胶质细胞在诱导大脑内部同步的神经波模式中起着核心作用。在本文中，我们证明了在自旋轨道扭矩振荡器神经元的基础重金属层中注入射频信号，模仿神经胶质细胞实现的神经元相同步效应。在时间“结合问题”的背景下，说明了这种相位耦合效应的潜在应用。我们还通过结合局部尖峰依赖性可塑性和星形胶质细胞诱导的神经相同步的概念来介绍由紧凑的神经映射器件启用的耦合神经元间隔 - 胃细胞网络的设计。
Astrocytes play a central role in inducing concerted phase synchronized neural-wave patterns inside the brain. In this article, we demonstrate that injected radio-frequency signal in underlying heavy metal layer of spin-orbit torque oscillator neurons mimic the neuron phase synchronization effect realized by glial cells. Potential application of such phase coupling effects is illustrated in the context of a temporal "binding problem". We also present the design of a coupled neuron-synapse-astrocyte network enabled by compact neuromimetic devices by combining the concepts of local spike-timing dependent plasticity and astrocyte induced neural phase synchrony.
