(A–B) Patch-clamp recording shows that ACh evokes a cation current in RIB. (A) Sample traces. (B) I-V relationship. n ≥7.
(C–D) ACh-gated current in RIB requires UNC-29 and ACR-16. Voltage: -60 mV. (C) Sample traces. (D) Bar graph. n=6. **p<0.002 (t test).
(E–F) Patch-clamp recording shows that ACh evokes a Cl− current in AIZ. Shown in (E) are sample traces. (F) I–V relationship. Low Cl−: 25 mM. High Cl−: 140 mM. n ≥5.
(G–H) ACh-gated Cl− current requires ACC-2. Voltage: −60 mV. (G) Sample traces. (H) Bar graph. n ≥6. **p<0.009 (t test).
All error bars: SEM. ACh: 1 mM.
