Abstract
It has long been known that stimulation of the medial medulla in the decerebrate animal produces bilateral inhibition of muscle tone. In the present study we have found that transection of the brainstem at the ponto-medullary junction attenuates this inhibition. An interaction between medullary and rostal brainstem systems is responsible for the medullary inhibition phenomenon. A similar interaction may produce the inhibition of muscle tone seen in REM sleep.
摘要
长期以来，人们都知道在去大脑动物中刺激延髓内侧会产生双侧肌张力抑制。在本研究中，我们发现脑桥 - 延髓交界处的脑干横断会减弱这种抑制。延髓和脑桥上部脑干系统之间的相互作用导致了延髓抑制现象。类似的相互作用可能导致在快速眼动睡眠中出现的肌张力抑制。
