A) Anatomical representation for specific regions chosen for microdissection. Sagittal section of a rainbow trout brain; TEL = telencephalon, T = optic tectum, HYP = hypothalamus, CER = cerebellum, MED = medulla. I Telencephalic coronal section ➊ represents striato-amygdalar complex (subpallium). II Diencephalic coronal section ➋ hypothalamic region sampled. III Brainstem coronal section ➌ raphé. B) Time line of experimental design. Days 1–7 fish were acclimated to the experimental tanks. A pretest blood sample was taken following acclimation, and fish were allowed to recover for three days. Training (CS + US) occurred daily over the next week, with testing on the following day. Fifteen minutes after the initiation of testing terminal blood and brain samples were collected for analysis.
