Abstract

The electrical slow-wave activity of the human small intestine has been simulated by a chain of 64 coupled electronic relaxation oscillators. The model simulates the frequency gradient of recorded patoentials in the human small intestine and when transected, behaves in a similar way to the transected canine small intestine. The model exhibits a spontaneous effect whereby several adjacent oscillators periodically are in the same state. This effect travels down the model in the time of 20-30 min.

摘要

人体小肠的电慢波活动已通过由64个耦合电子弛豫振荡器组成的链进行模拟。该模型模拟了人体小肠中记录电位的频率梯度，并且在横断时，其行为方式与横断的犬小肠相似。该模型表现出一种自发效应，即几个相邻的振荡器会周期性地处于相同状态。这种效应在20 - 30分钟的时间内沿模型向下传播。
