the threshold concentration producing these effects was between 1 and 2 mum.6 5-ht produced a rapid depolarization of the ganglion cell membrane which was followed by an after-hyperpolarization.7 bradykinin either produced no measurable change in ganglion cell resting potential or only very small , transient depolarizations.8 the depression of transmission , enhancement of intrinsic facilitation and the depolarization of the ganglion cell membrane induced by 5-ht may indicate more than one mode of action of this amine at the ganglionic synapse .
