| Abstract: | This study compared the contribution of the Ca2+‐activated Cl? conductance to the electroolfactogram (EOG) evoked by different odorant classes between the marine Cabinza grunt Isacia conceptionis and rainbow trout Oncorhynchus mykiss. The Ca2+‐activated Cl? channel blocker niflumic acid significantly diminished odorant responses in O. mykiss, but had no effect on the EOG in I. conceptionis, supporting the notion that Ca2+‐activated Cl? channels may not operate as odorant transduction current amplifiers in this marine teleost. |
