Abstract

Acetylcholine (ACh)-induced currents were recorded from the voltage-clamped cell body of the fast coxal depressor motoneurone of the cockroach Periplaneta americana, at membrane potentials in the range -120 mV to -60 mV. In the presence of histrionicotoxin (HTX) (1.0 × 10^-6 M), ACh currents were blocked. The blocking action of HTX was voltage-dependent, being more negative membrane potentials.
