Mean (± SEM) concentrations of A) serotonin (5-HT) and C) dopamine (DA) are significantly (*) elevated in the hypothalamus of non-escaping trout (hatched bars) compared to fish that learned to escape. Hypothalamic monoamine concentrations were measured following presentation of CS alone on day 8, after 7 days of CS+US pairings. There was no significant effect of CS+US pairing on concentrations of B) 5-hydroxyindoleacetic acid (5-HIAA) or D) dihydroxyphenylacetic acid (DOPAC) in this region.
