Kelso及其同事（1992）使用多传感器SQUID（超导量子干涉装置）阵列进行了一项实验，该实验结合了来自三个不同来源的信息：感知，运动反应和大脑信号。当声刺激频率系统地改变时，在运动行为和大脑信号的临界频率处发生协调的自发过渡。在物理和生物学系统中，类似的质性转变是已知的，例如人手运动协调性的变化（Kelso 1981，1984）。在本文中，我们开发了一个理论模型的基础上，从协同学（哈肯1983年，1987年）和非线性振荡器理论的跨学科领域的方法，再现了主要的实验功能非常好，并提出了一个基本的生物物理耦合的制定。
An experiment using a multisensor SQUID (superconducting quantum interference device) array was performed by Kelso and colleagues (1992) which combined information from three different sources: perception, motor response, and brain signals. When an acoustic stimulus frequency is changed systematically, a spontaneous transition in coordination occurs at a critical frequency in both motor behavior and brain signals. Qualitatively analogous transitions are known for physical and biological systems such as changes in the coordination of human hand movements (Kelso 1981, 1984). In this paper we develop a theoretical model based on methods from the interdisciplinary field of synergetics (Haken 1983, 1987) and nonlinear oscillator theory that reproduces the main experimental features very well and suggests a formulation of a fundamental biophysical coupling.
