Tonic Supraspinal Mechanisms Influencing the Intestino – Intestinal Inhibitory Reflex

Johansson, B., O. Jonsson and H. Ljung. Tonic supraspinal mechanisms influencing the intestino‐intestinal inhibitory reflex. Acta physiol. scand. 1968. 72. 200–204. Supraspinal control mechanisms acting on the spinal intestino‐intestinal inhibitory reflex have been studied with regard to their possible tonic influence. The experiments which were done on chloralose or chloralose‐urethane anesthetized, vagotomized cats involved acute experimental lesions at the mesencephalic and cervical spinal levels of the CNS. The results indicate that the autonomic reflex is subjected to facilitation from suprabulbar areas and to strong tonic suppression from bulbar structures.
