The overall goal of my lab is to identify how aberant neuronal signaling and information processing occurs in the basal ganglia at the cellular and network level in Parkinson's disease (PD). Currently, an understanding of the pathophysiology that contribute to the motor and non-motor complications of this disease remains incomplete.
To undertake this task, my laboratory employs a variety of electrophysiological techniques to monitor neuronal activity in brain slices and neuronal activity from multiple brain regions from anesthetized or freely moving normal and parkinsonian animals; the former approach permits us to monitor changes in ion channel activity in neurons while the latter provides information about the neural network and oscillatory changes in PD. We also employ behavioral testing of parkinsonian animals, immunohistochemistry and optogenetics to complement the electrophysiological data.
From our work, we hope that important and innovative findings will emerge that will lead to novel treatment paradigms for managing motor and non-motor symptoms of PD. The specific research goals of my lab are outlined below:
