英文摘要
Project Summary
Parkinson’s disease (PD) is the second most common neurodegenerative disease associated with aging. The
disease is characterized by motor symptoms attributed to the loss of mesencephalic dopaminergic neurons and
their innervation to the basal ganglia macrocircuit. In patients and animal models of PD, this macrocircuit
exhibits aberrant activity patterns including synchronous, rhythmic bursting of neurons in the external globus
pallidus (GPe). However, the factors that shape these synchronous and temporallystructured events in PD
remain unknown. It is our overarching hypothesis that GABAergic inputs shape the activity level, pattern, and
synchrony of both parvalbumin and Npas1 neurons within the GPe. Using cell and circuitspecific tools, we
will investigate the connectivity of striatal inputs and local collateral inputs to parvalbumin and Npas1 neurons
within the GPe and how this connectivity becomes altered in the chronic 6OHDA lesion model of PD.
Furthermore, we will determine how parvalbumin and Npas1 neurons and their striatal inputs are involved in
motor function and dysfunction. The proposed experiments capitalize on a combination of cuttingedge
approaches that will overcome obstacles that had impeded progress until now. These approaches include viral
gene delivery, Crelox recombination, optogenetics, chemogenetics, electrophysiology, and fiber photometry.
Additionally, anatomical, analytical, and computational approaches will be used to help interpret research
findings. The successful achievement of these aims will significantly advance our understanding of the
mechanisms underlying PD and, in doing so, promote the development of new therapies for PD patients.
