[Effect of monoamines on the responses of frog spinal motor neurons mediated by non-NMDA glutamate receptors].

Abstract

Adrenaline, dopamine and 5-hydroxytryptamine enhanced fast desensitizing responses of frog spinal motoneurons evoked by L-glutamic acid. Monoamines also enhanced late components of dorsal root EPSP's of motoneurons. These effects of monoamines were prevented by ketamine. Slow in desensitizing responses evoked by L-glutamic acid and EPSP's of motoneurons evoked by stimulation of the reticular formation were not influenced by monoamines.
