Popis: A study is performed of the effect of the convulsants picrotoxin and bicuculline, blockers of GABA-dependent Cl−-conductivity, on the rate of desensitization of muscimol-induced36Cl− entry into synaptoneurosomes isolated from rat cortex. Both picrotoxin and bicuculline, despite the difference in the mechanisms of inhibition of the GABA receptor/Cl− ionophore complex, markedly reduce the rate of desensitization. However, the initial moment of the action of both convulsants is characterized by inhibition of Cl− transport alone, without a drop of the rate of desensitization.
