... to slicing, the brainstem–spinal cord was transferred to a 5 ml Sylgard-coated Petri dish that was constantly perfused with oxygenated aCSF. The brainstem–spinal cord was then pinned ventral side up. The 4th branch (rootlet) of the vagus nerve was isolated, as it is composed largely of axons that control...

...E. W. Taylor; C. A. C. Leite; L. H. Florindo; T. Beläo; F. T. Rantin SUMMARY The role of the parasympathetic nervous system, operating via the vagus nerve, in determining heart rate ( f H ) and cardiorespiratory interactions was investigated in the neotropical fish Piaractus mesopotamicus . Motor...

..., and, consequently, the terminal field (sensory area)of their afferents (glossopharyngus and vagus) in the medulla must be an important site for the integration of chemoreceptor and baroreceptor signals. This investigation explored whether fish have glutamatergic mechanisms in the vagal sensory area (Xs) that could...

... of ventilation, at least over the range studied. Inhibition of vagus nerve conduction at 5°C was achieved using localized nerve block. This led to an increase in apneic heart rate and abolished the ventilatory tachycardia. The results of this study indicate that vagal projections are involved...

...G. P. Courtice ABSTRACT The effect of temperature on the action of the vagus nerve on the heart was studied in the toad Bufo marinus . Experiments were performed on two groups of toads, in one the heart was perfused at a constant rate with oxygenated Ringer’s solution and in the other...
