在理论和计算神经科学中使用了各种各样的神经元模型,其中,单室模型是一种流行的模型。这些模型没有明确地包括树突或轴突,并且范围从Hodgkin-Huxley(HH)模型到各种风格的整合和激发(IF)模型。主要类别的模型在尖峰启动的方式上有所不同。哪一个是最现实的?从一些一般认识论的考虑开始,我展示了实在论的概念有两个维度:经验内容(模型可以产生的预测)和经验准确性(这些预测是否正确)。然后,我检查的现实主义的主要类别的单室模型沿着这两个方面,根据最近的实验证据。
A large variety of neuron models are used in theoretical and computational neuroscience, and among these, single-compartment models are a popular kind. These models do not explicitly include the dendrites or the axon, and range from the Hodgkin-Huxley (HH) model to various flavors of integrate-and-fire (IF) models. The main classes of models differ in the way spikes are initiated. Which one is the most realistic? Starting with some general epistemological considerations, I show that the notion of realism comes in two dimensions: empirical content (the sort of predictions that a model can produce) and empirical accuracy (whether these predictions are correct). I then examine the realism of the main classes of single-compartment models along these two dimensions, in light of recent experimental evidence.
