The development of animal models that reproduce the selective and progressive loss of nigral dopamine neurons characterizing Parkinson’s disease has opened new possibilities to study the disease evolution. Here magnetic resonance spectroscopy imaging was used to follow up the distributions of metabolites in key basal ganglia components in two rat models of progressive parkinsonism at three time points over a period of 120 days following injury. First results on overtime changes in NAA and glutamate repartition will be presented. Completion of this project may provide novel insights onto the pathological alterations associated with the progression of the neurodegenerative process.
