The presynaptic and postsynaptic actions of 5 hydroxy tryptamine in crustacea


, : The presynaptic and postsynaptic actions of 5 hydroxy tryptamine in crustacea. Comparative Biochemistry and Physiology C Comparative Pharmacology 54(2): 67-70

5-Hydroxytryptamine [5HT; 10 nmol] increased the amplitude and facilitation of the EJP [excitatory junctional potential] in Eupagurus bernhardus. 5HT changed the EJP from a single transient depolarization to multiple depolarizations. These actions of 5HT are probably presynaptic.

The myoclonus induced by tryptamine...
