serotonin

Acronym: 
NULL
Definition: 
An important neurochemical whose effects upon the human brain include mood elevation. Production of serotonin in the brain is increased by ingestion of the amino acid tryptophan (a chemical precursor to serotonin) and the pharmaceutical anti-depressant Prozac (trademarked product of Eli Lilly & Company). In 1997, Marianne Regard and Theodor Landis discovered that humans afflicted with hemorrhagic lesions in the brain (cause of abnormal serotonin activation/production) often became "passionate culinary afficionados."
