Effects of phenylalanine diet on brain serotonin in the rat.
Hooded rats fed diets rich in phenylalanine showed poorer performance on the Hebb-Williams maze than controls, as well as decreased brain serotonin levels. There did not appear to be a causal relationship between these findings, and the findings do not appear to be attributable either to a generalized behavioral defect or to inadequate dietary intake.
