Central ventilatory and cardiovascular actions of serotonin in trout

Highlights • In trout central injection of 5-HT stimulates ventilation and blood pressure. • 5-HT1/2 receptors may be responsible for the central effects of 5-HT. • Intra-arterial injection of 5-HT provokes a biphasic change in blood pressure. • Endogenous 5-HT may act as a potent cardio-ventilatory...

Summary:Highlights • In trout central injection of 5-HT stimulates ventilation and blood pressure. • 5-HT1/2 receptors may be responsible for the central effects of 5-HT. • Intra-arterial injection of 5-HT provokes a biphasic change in blood pressure. • Endogenous 5-HT may act as a potent cardio-ventilatory neuroregulator.
