Behavioral impairments in mice following administration of the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) require large depletions in striatal dopamine content and are often transient. In this paper, we describe a simple and inexpensive test that measures long-term behavioral deficits in mice treated with moderate doses of MPTP. These measures are significantly correlated with the loss of striatal dopamine and immunoreactivity of the dopamine transporter, vesicular monoamine transporter and tyrosine hydroxylase. In addition, behavioral impairments on the measures were reversed following L-DOPA administration. Employment of this test will allow for more efficacious use of mice in PD research, as well as provide more sensitive measures of behavioral improvement following potential therapeutic or neuroprotective interventions.
