[Effective of surgical decortication on cardio-cardiac reflexes in cats]

The cardio-cardiac reflexes were studied in unanesthetized curarized cats before and after surgical decortication. The data obtained showed three varieties of the cortical adaptation: the inhibition of the reflexes, their facilitation, and the effects of regulatory "silence". Under normal condition the cortical function seems to exert modulating influences on the cardio-cardiac reflexes by way of the afferent vagal nucleus.
