令人印象深刻的生物节律多样性无疑表明自主周期性过程有助于生命过程的协调。这里提出的问题是，“哪些时间组织模式[长划线]（如果有的话）[长划线]可能是由先天振荡装置（例如电子振荡器、分泌细胞、自发活动神经元或个体动物）群体中的弱相互作用产生的？”通过数学分析、电子实验和数字计算机模拟，可以找到周期性过程的性质和所涉及的相互作用类型的函数答案。对于“广义张弛振荡器”群体，发现了多种模式中任意模式下相互同步的阈值条件。有人提出，这种自吸群落可能存在于个体后生动物和植物中，作为观察到的其生理过程的昼夜协调的基础。
The impressive variety of biological rhythms leaves no doubt that autonomously periodic processes contribute to the co-ordination of life-processes. The question here raised is, "What modes of temporal organization[long dash]if any[long dash]could result from weak interactions in a population of innately oscillatory devices (e.g. electronic oscillators, secretory cells, spontaneously active neurons, or individual animals)?" By mathematical analysis, electronic experiments, and digital computer simulation, answers are found as functions of the nature of the periodic processes and the kind of interactions involved. For populations of "generalized relaxation oscillators", threshold conditions are discovered for mutual synchronization in any of a variety of modes. It is proposed that self-entraining communities of this sort may exist within individual metazoan animals and plants as the basis of the observed diurnal coordination of their physiological process.
