神经脉冲传播的物理背景:热量和能量

On physical background of nerve pulse propagation: heat and energy

Jüri Engelbrecht, Kert Tamm, Tanel Peets

摘要:

最近的研究揭示了轴突中神经信号的复杂结构。除了电信号外,在许多实验研究中还检测到机械和热效应。在本文中,热生成的数学模型进行了分析的一般模型的框架内得出的作者。热产生的主要机制似乎是焦耳加热和吸热和放热反应。内部变量的概念允许模拟这些反应的典型热松弛。整个信号的一般能量平衡基于负责出现信号分量的物理机制来分析。最后提出了一些有待进一步研究的问题。

英文摘要:

Recent studies have revealed the complex structure of nerve signals in axons. Besides the electrical signal, mechanical and thermal effects are also detected in many experimental studies. In this paper, the mathematical models of heat generation are analysed within the framework of a general model derived earlier by the authors. The main mechanisms of the heat generation are seemingly the Joule heating and endo- and exothermic reactions. The concept of internal variables permits to model the heat relaxation typical to these reactions. The general energy balance of the whole signal is analysed based on physical mechanisms responsible for emerging the components of a signal. Some open questions are listed for further studies.
