Further evidence for the differentiation, by suberyldicholine and cytisine, of two distinct Cl-dependent responses.A, Effect of 500 nm αCTx ImI on the responses to 100 μm ACh and 20 μmsuberyldicholine of a buccal cell showing a prominent sustained element in the two-component Cl-dependent response. Note the selective elimination in the ACh response of the rapidly desensitizing element and a failure of the toxin to affect the response to suberyldicholine. The periodic rapid deflections seen in the ACh records inA represent spontaneous synaptic activity.B, Effect of 1 μm cytisine (applied in the control tube only) on the ACh response of a buccal cell to 100 μm ACh and 10 μm suberyldicholine. Cytisine can be seen to block only the rapidly desensitizing element of the ACh response, whereas it has no effect on the response to suberyldicholine.
