The Center's most recent other conferences were on "Melatonin in Humans" (Vienna, Austria; November 1985) and "The Pharmacology of Memory Disorders Associ ated with Aging" (Zurich, Switzerland; January 1987). The decision to organize this conference was based on the perception that major changes had recently occurred in society's uses of phenylalanine and phenylalanine-containing products, and on the belief that a meeting of scientists and physicians who work on the amino acid's neurological effects could both catalyze additional research on these effects and assist regula tory bodies in formulating appropriate public policies relating to the use of these products: phenylalanine, in both its L- and D-forms, has apparently become a popular sales item at "health-food" stores, and thus is now being consumed by a fairly large number of people, in the absence of the other
