Thg causes an inward current in SMC isolated from rat small IPA. Below, the typical trace of the noisy inward current developing in SMC isolated from small IPA in response to 100 nM Thg. Above, the expanded sections of the same trace showing the dramatic increase of single-channel activity. Holding potential −80 mV, intracellular solution – Cs methanesulphonate, 10 -mM BAPTA. Lines indicate zero current level. Traces shown are typical of five to seven experiments.
