标题： Comment on "Energy and information in Hodgkin-Huxley neurons"

摘要： 在最近的一篇论文[A. Moujahid, A. d'Anjou, F. J. Torrealdea 和 F. Torrealdea, Phys. Rev. E{\bf 83}, 031912 (2011)]中，作者通过使用霍奇金-赫胥黎（HH）模型计算了神经元放电所消耗的能量。采用的HH模型的能量消耗率导致了一个{\it 负的}的能量消耗，这意味着从HH神经元到一个源的能量传递在物理上是奇怪的，尽管他们将其解释为生化能量成本。我提出了一种替代的功率消耗表达式，这导致了一个{\it 正数}的HH神经元中消耗的能量，并提出了与他们论文中的结果进行比较的一些模型计算。 显示英文摘要

摘要： In a recent paper [A. Moujahid, A. d'Anjou, F. J. Torrealdea and F. Torrealdea, Phys. Rev. E {\bf 83}, 031912 (2011)], the authors have calculated the energy consumed in firing neurons by using the Hodgkin-Huxley (HH) model. The energy consumption rate adopted for the HH model yields a {\it negative} energy consumption meaning an energy transfer from an HH neuron to a source which is physically strange, although they have interpreted it as a biochemical energy cost. I propose an alternative expression for the power consumption which leads to a {\it positive} energy consumed in an HH neuron, presenting some model calculations which are compared to those in their paper.
