讨论的问题是感觉通路中单个神经元的放电与主观感受之间的关系。结论被表述为以下五个教条：为了理解神经功能，人们需要在细胞水平上观察相互作用，而不是在更宏观或微观的水平上，因为行为取决于这些细胞间相互作用的组织模式。感觉系统被组织起来，以最少数量的活跃神经元实现尽可能完整的感觉刺激表示。感觉神经元的触发特征与经验以及发育过程中的冗余刺激模式相匹配。感知对应于从非常多的高级神经元中选择的一小部分神经元的活动，每一个都对应于一个外部事件的模式，该模式的复杂程度由一个词来表示。在这样的神经元中，高脉冲频率对应于触发特征存在的高度确定性。这些推测性教条的概念的发展，它们的实验基础，以及它们的一些局限性进行了讨论。
The problem discussed is the relationship between the firing of single neurons in sensory pathways and subjectively experienced sensations. The conclusions are formulated as the following five dogmas:To understand nervous function one needs to look at interactions at a cellular level, rather than either a more macroscopic or microscopic level, because behaviour depends upon the organized pattern of these intercellular interactions.The sensory system is organized to achieve as complete a representation of the sensory stimulus as possible with the minimum number of active neurons.Trigger features of sensory neurons are matched to redundant patterns of stimulation by experience as well as by developmental processes.Perception corresponds to the activity of a small selection from the very numerous high-level neurons, each of which corresponds to a pattern of external events of the order of complexity of the events symbolized by a word.High impulse frequency in such neurons corresponds to high certainty that the trigger feature is present.The development of the concepts leading up to these speculative dogmas, their experimental basis, and some of their limitations are discussed.
