Coumarin effects on amino acid levels in mice prefrontal cortex and hippocampus.

Coumarin is a compound known to be present in a wide variety of plants, microorganisms and animal species. Most of its effects were studied in organs and systems other than the central nervous system. The present work evaluated the effect of coumarin administration on the levels of gamma-aminobutyric acid (GABA), glutamate (GLU), glycine (GLY) and taurine (TAU) in the prefrontal cortex and hippocampus of mice.
