Injecting fish with the 5HT2A receptor silent antagonist ketanserin blocked the 5-HT-typical EOD enhancement in τP2 (a) but had no effect on amplitude response to 5-HT injection (b). Pre-treating fish with ketanserin followed by 5HT1A antagonist, WAY100635, does not block enhancement of τP2, rather the ketanserin+WAY100635 response is greater than response to WAY100635 alone (a). Amplitude responses to challenge with ketanserin+ WAY100635 were no different than responses to WAY100635 given alone (b). Responses were measured relative to individual baseline [(peak − baseline)/baseline] and error bars represent mean ± 95% confidence intervals of combined data. A solid black circle denotes statistically significant differences ( p<0.05) between responses to ketanserin pre-treatment and saline pre-treatment challenge responses as determined by one-tailed Student’s t-test.
