Compared with vehicle, only intracerebroventricular injection of PACAP significantly ( P <0.05) elevated the ventilation frequency and the ventilation amplitude, but both peptides significantly increased the total ventilation ( ). However...

... tachykinins, particularly NPγ,produce a strong hypoventilatory response in a teleost fish and so suggest that endogenous tachykinins may be differentially implicated in neuroregulatory control of ventilation. neuropeptide γ substance P neurokinin A ventilatory control intracerebroventricular injection...
