Typical examples of the effects or lack of an effect of acutely applied estradiol (E2) on responses evoked by histamine agonists. (A and B) E2 potentiated betahistidine (BH) depolarization to 186 ± 17% of the pretreatment amplitude, but neither potentiated nor attenuated hyperpolarizations caused by dimaprit (DI in C and D) or imetit (IM in E and F).
