... that serotonin exerts a permanent excitatory modulation on the central respiratory rhythm generator but depresses the inspiratory motor output to the genioglossus muscle. In vivo experiments confirmed that increasing endogenous serotonin levels decreases the inspiratory activity of the genioglossus and elicits...

... during hypoxia compared to appropriately grown littermates. Growth retarded rat fetuses exhibited marked changes of the monoamine metabolism in the brain inasmuch as basal levels of serotonin and its main metabolite were low while an inappropriate acceleration of the serotonin synthesis rate took place...

In each case...
