Abstract
Previous reports have suggested that protein and tryptophan deprivation might be associated with decreased mental functioning. To provide additional relevant data, two groups of rats—one protein- and tryptophan-deprived and one reared normally—were tested for learning ability in a modified Hampton Court maze. Analysis indicated that protein and tryptophan deprivation did not result in inferior maze performance.
