Abstract：
:In neonates, ventilatory responses to hypoxia are 'biphasic,' with an augmentation followed by a decline. The hypoxia-induced augmentations in ventilation are attenuated and the depressions are accentuated following denervation of the peripheral chemoreceptors. Piglets that were decerebrated at a rostral mesencephalic level exhibited these hypoxia-induced depressions. These depressions were lessened following transection through the caudal mesencephalon. Mesencephalic mechanisms play a fundamental role in the brainstem regulation of ventilatory responses to hypoxia.
