Tectal neurons have fewer branches in n-3 PUFA-deprived brain. A, Total branch number, (B) total dendritic length, and (C) average branch length were analyzed in tectal neurons in tadpoles from frogs fed the n-3 PUFA-adequate (Ade) or deficient (Def) diets for 60 weeks. Data are mean ± SEM. N = 24 neurons for the adequate, and n = 25 neurons for the deficient group, with one neuron analyzed per tadpole. Tadpoles analyzed were obtained from 6 and 5 frogs, respectively. *p < 0.05, **p < 0.01, ***p < 0.001; asterisks above gray bars indicate comparison with time-matched adequate group. (Tukey test).
