New dendrite branch addition is altered in neurons from tadpoles with n-3 PUFA deficiency. The number of new branches and of stable branches was counted every 24 h to determine dendrite dynamics. The absolute number of (A) new branches added and (B) stable branches were reduced in the n-3 PUFA-deficient (Def) group. However, as percentage of total, the number of new branches (C) and stable branches (D) was not changed. Data are mean ± SEM. N = 24 for the adequate (Ade) and n = 25 for the deficient group. *p < 0.05, **p < 0.01, ***p < 0.001.
