1 The effects of 5-hydroxytryptamine (5-HT) on ganglionic transmission and on intrinsic modulation of transmission have been re-examined and compared with the effects of bradykinin by means of electrophysiological techniques.2 Early facilitation, which is maximal 40-75 ms after a conditioning stimulus, was considerably enhanced by 5-HT. This enhancement was concentration-dependent, the threshold concentration lying between 0.1 and 1 muM. With concentrations of 5-HT 10 muM or greater, there was… CONTINUE READING
