Three Component Test of Dopaminergic FunctionThree Component Test


The three component test is a rapid and efficient technique that can be used to profile the effects of drugs on limbic and striatal dopaminergic function and neurochemistry in the same mice.

The three components of the test (measured as part of a single experiment) are :-

     •     Locomotor activity (a mesolimbic mediated behaviour)
     •     Stereotyped  licking, biting and chewing (extrapyramidal-mediated behaviours)
     •     Measurement of striatal levels of dopamine and its metabolites (neurochemical


The three component test can be used to :-

     •     Identify novel antipsychotics (following administration of amphetamine which
           can be given in divided doses)
     •     Profile dopamine reuptake inhibitors, dopamine releasing agents and other dopamine
     •     Demonstrate that drugs have little effect on the dopamine system in vivo.
