Noradrenaline (NA) and dopamine (DA) levels were studied in the forebrain of acute immobilized cats and in cerveau isolé preparations. A gradual decrease in NA and DA was observed one and two hours after high mesencephalic transection, while the amount of NA increased in acute immobilized cats after the cessation of ether anaesthesia. These changes in NA level are consistent with the observations suggesting an inverse relationship between NA and cortical deactivation. The decrease of DA with an exaggeration of spindle activity and increased synchronizing effect of basal forebrain stimulation indicate that the spindle-increasing effect of DA suggested by several authors requires the contribution of the brain stem.
研究了急性固定猫前脑及孤立脑标本中去甲肾上腺素（NA）和多巴胺（DA）的水平。在中脑高位横断后1小时和2小时观察到NA和DA逐渐减少，而在停止乙醚麻醉后，急性固定猫的NA含量增加。NA水平的这些变化与提示NA与皮质失活呈负相关的观察结果一致。DA的减少伴随着纺锤体活动的增强以及基底前脑刺激同步效应的增加，这表明几位作者提出的DA的纺锤体增强效应需要脑干的参与。
