Popis:	External miniature postsynaptic potentials were recorded from fibres of the metathoracic retractor unguis muscle of Schistocerca gregaria . At concentrations from 0.4 to 0.5 bee units/ml the venom of European Philanthus triangulum causes a decrease in amplitude and in half-decay time of miniature potentials. It is suggested that the venom, partially blocks the current by shortening the ion-channel open-life-time in the postsynaptic membrane.
