This paper describes the possibility that rostal pontine neuronal structures cause the parallel suppression of postural tone and respiration evoked by stimulation of the dorsal tegmental field (DTF) of the pons in decerebrate cats. Stimulation of the DTF along the midline decreased both diaphragmatic activity and the bilateral tone of the hind-limb extensor muscles. Pontine neuronal structures located rostrally to the DTF, from which antidromically activated units could be recorded on stimulation of the DTF, were studied. Antidromic spikes were recorded in and near the nucleus reticularis pontis oralis. Tonic electrical stimulation of these sites caused parallel suppression of postural tone and respiration. These suppressive effects were almost similar to those elicited by the DTF stimulation.
本文描述了在去大脑猫中，脑桥嘴侧神经元结构导致由刺激脑桥背侧被盖区（DTF）所诱发的姿势紧张和呼吸平行抑制的可能性。沿中线刺激DTF会降低膈肌活动以及后肢伸肌的双侧紧张度。对位于DTF嘴侧的脑桥神经元结构进行了研究，在刺激DTF时可从这些结构中记录到逆向激活的单位。在脑桥嘴侧网状核及其附近记录到了逆向动作电位。对这些部位进行强直电刺激会导致姿势紧张和呼吸的平行抑制。这些抑制效应与DTF刺激所引发的效应几乎相似。
