Levels of α-amino acids in hypothalamus (A) and telencephalon (B) of rainbow trout 6 h after intraperitoneal administration of 0.5 mL⋅100 g-1 body mass of saline solution alone (control) or containing 40 μmol⋅mL-1 of L-leucine, 40 μmol⋅mL-1 of L-valine, or 40 μmol⋅mL-1 of L-proline. Each value is the mean + SEM of n = 10 fish per treatment. Different letters indicate significant differences (P < 0.05) between different groups. P-values are: for hypothalamus (A), C vs L = 0.448, C vs V = 0.514, C vs P = 0.037, L vs V = 0.809, L vs P = 0.149, V vs P = 0.287; and for telencephalon (B), C vs L = 0.338, C vs V = 0.024, C vs P = 0.020, L vs V = 0.212, L vs P = 0.286, V vs P = 0.698.
