This is a segment of a longer animation created for Brookhaven National Laboratory. (You may view the entire animation and learn about GVG on this page of Brookhaven's web site.)

The animation demonstrates how GVG (or gamma vinyl-GABA) appears to prevent the biochemical and behavioral effects of nicotine and cocaine by altering the way brain cells communicate.

Neurotransmitters such as GABA (which control dopamine production) are themselves controlled by enzymes. This portion of the animation depicts collection of GABA by the enzyme GABA transaminase (G-t) inside a GABA cell.
