My laboratory is mainly involved in investigating electron microscopic/immunocytochemical changes in synapses within the brain following various drug treatment procedures or lesions of the nigrostriatal pathway, as a model for Parkinson’s disease (PD), and correlating these findings with functional/protein changes using in vivo microdialysis/westerns and motor behaviors in mice. Using a new progressive mouse model of PD developed in my lab, by administering increased doses of the toxin, MPTP, we have found that exposure of mice to a socially enriched environment can, after the initiation of the loss of dopamine, slow down or block the neurochemical and motor behavioral deficits due to continued treatment with MPTP.
