title: Effects of tryptophan depletion on Poggendorff illusion, corner Poggendorff illusion, and attention.
abstract: The effects of a tryptophan-free amino acid mixture on Poggendorff illusion, corner Poggendorff illusion, and attention were investigated with 12 male subjects who ingested either a balanced amino acid mixture or a tryptophan-free mixture, the latter known to cause a marked depletion of brain tryptophan and serotonin. No significant difference between the two mixtures on the perceptual illusions was found.
