Gene-Altered Mouse May Provide New Insights To Parkinson's Disease, Substance Abuse And Schizophrenia

...man measured how long dopaminestays in the synapse after it is released. Their measurements showed thatin a normal mouse, the dopamine is scavenged by the transporter proteinin less than one second. However, in the knockout mice with no dopaminetransporter protein, the dopamine stays in the synapse at leas...
