Lutein (A), zeaxanthin (B), and β-carotene (C) concentrations in each brain region
of infant monkeys either BF (n = 8), SF (n = 8),
or UF (n = 7) for 6 mo. Values are presented as mean ± SD. Diet and
area effects were determined by 2-way ANOVA. Labeled means for each tissue without a
common letter differ, P < 0.05, by 1-way ANOVA or Welch's test
followed by Bonferroni or Dunnett's T3 pairwise post-hoc tests. The lower limit of
detection for carotenoids is 0.2 pmol. BF, breastfed; CB, cerebellum; conc,
concentration; GM, gray matter; HP, hippocampus; MC, motor cortex; ND, not detected;
OC, occipital cortex; PFC, prefrontal cortex; SF, supplemented formula-fed; ST,
striatum; STC, superior temporal cortex; UF, unsupplemented formula-fed; WM, white
matter.
