This study was undertaken to describe details of the location and cellular morphology of functionally identified (inspiratory or expiratory) external and internal intercostal motoneurons on the basis of intracellular injection of horseradish peroxidase (HRP). Sixty HRP-labeled motoneurons were examined; 44 in transverse, 16 in sagittal sections. In the(More)
Respiration was recorded in unanaesthetized rats breathing air, or CO2 in air, 4-8 days after injection into the rostral brainstem at the level of the dorsal raphe nucleus of either a catecholaminergic neurotoxin, a serotoninergic neurotoxin, or the vehicle (0.5% ascorbic acid) of these drugs. Some rats were pretreated with the noradrenergic neurone(More)
Transganglionic transport of horseradish peroxidase or lectin-conjugated horseradish peroxidase from an application site in the cervical trunk of the glossopharyngeal (IXth cranial) nerve of the rat produced extraperikaryal reaction product characteristic of axon terminal processes in three regions of the brain stem: (1) the nucleus of the tractus(More)
Respiratory patterns have been studied in awake and halothane anaesthetised rats. Tidal volume (VT) was shown to be age-sensitive over 44-200 days; failure to account for this gave the appearance of an increased ventilatory sensitivity to CO2 with age. Inspiration of CO2 (0-10.5%) produced linear responses of VT whereas frequency responses stabilised at 6%(More)
