Mean (± SEM) concentrations of A) serotonin (5-HT), B) 5-hydroxyindoleacetic acid (5-HIAA), C) dopamine, (DA), and D) dihydroxyphenylacetic acid (DOPAC) are significantly (*) elevated in the striato-amygdalar complex (subpallium) of non-escaping trout (hatched bars) compared to fish that escaped. Subpallial monoamine concentrations were measured following presentation of CS alone on day 8, after 7 days of CS+US pairings.
