摘要

本研究创新性地将基于Miller效应的memcapacitor引入到经典的Hodgkin-Huxley (HH)神经元系统中,提出了一种改进的memcapacitor Hodgkin-Huxley (MC-HH)神经元模型。该模型通过用记忆电容元件取代传统的膜电容,充分利用了记忆电容独特的记忆特性,显著增强了模型的动态行为和对生物神经元历史依赖特性的模拟能力。在研究过程中,采用分岔图和相轨迹图等非线性动力学分析方法,研究了模型在memcapacitor影响下的复杂动力学行为,以及高斯白噪声驱动下的逻辑随机共振现象。结果表明,该模型表现出双稳态和滞后现象,揭示了通过刺激电流和触发通量协同调节“触发通量-膜电容-电活动-能量代谢”的机制。此外,该模型不仅继承了经典HH神经元在实现可靠逻辑运算方面的优势,而且利用memcapacitor独特的存储特性,为神经形态计算的逻辑设计提供了新的调控维度,有望推动高度集成的神经形态芯片的发展。

Energy consumption analysis and logical stochastic resonance of Memcapacitor Hodgkin–Huxley neuron based on the Miller effect

Energy consumption analysis and logical stochastic resonance of Memcapacitor Hodgkin–Huxley neuron based on the Miller effect
This study innovatively introduces a memcapacitor based on the Miller effect into the classical Hodgkin–Huxley (HH) neuron system, proposing an improved Memcapacitor Hodgkin–Huxley (MC–HH) neuron model. By replacing the traditional membrane capacitance with a memcapacitive element, this model fully leverages the unique memory characteristics of the memcapacitor, significantly enhancing the model's dynamic behavior and its simulation capability for the history-dependent properties of biological neurons. During the research process, nonlinear dynamic analysis methods such as bifurcation diagrams and phase trajectory plots were employed to investigate the complex dynamic behaviors of the model under the influence of the memcapacitor, as well as the logical stochastic resonance phenomenon driven by Gaussian white noise. The results indicate that the model exhibits bistability and hysteresis phenomena, revealing the "trigger flux – membrane capacitance – electrical activity – energy metabolism" mechanism through the synergistic regulation of stimulus current and trigger flux. Furthermore, this model not only inherits the advantage of classical HH neurons in achieving reliable logical operations but also provides a new regulatory dimension for the logical design of neuromorphic computing by leveraging the unique memory characteristics of the memcapacitor, which holds promise for advancing the development of highly integrated neuromorphic chips.
