Effects of preincubation in either tyramine or octopamine on avoidance responses to 30 and 100% octanol. Wild-type animals were preincubated (6 h) in the presence or absence of TA or OA (4 mm) and then assayed for responses to 30 and 100% octanol. A, Outline of “adaptation” protocol. B, Effects of TA or OA on sensitivity to 100% octanol after preincubation in either TA or OA. C, Effects of TA or OA on sensitivity to dilute (30%) octanol after preincubation in either TA or OA. Data are presented as mean ± SE and analyzed by a two-tailed Student's t test. ***p < 0.001, significantly different from wild-type animals under identical incubation conditions. The number of trials is indicated under each bar.
