Abstract

Weanling mice were fed an amino acid-based diet supplemented with 0 or 11.3 μmol folic acid/kg diet for ∼ 38 days to study behavior and neurochemistry in folate deficiency. After ∼ 5 wk, mice fed the unsupplemented diet weighed ∼ 70% as much those fed the supplemented diet. After 2 wk, mice fed the unsupplemented diet consistently discarded (spilled) more food, and after ∼ 5 wk, they had spilled 3 times more than mice fed the supplemented diet. Serum folate, brain folate and brain S-adenosylmethionine of mice fed the unsupplemented diet were 4, 53, and 60% as high, respectively, as those of mice fed the supplemented diet. Pathologic changes were not evident in brain, spinal cord, or skeletal muscle of folate-deficient mice. The hypothalamic 5-hydroxyindole acetic acid/serotonin ratio and caudate dopamine, homovanillic acid, and 3,4-dihydroxyphenylacetic acid concentrations were lower in deficient than control mice. Folate-deficient mice develop a behavioral activity, food spilling, which may have a neurochemical basis in the serotonin and dopamine systems.
