This study identifies distinct GPe neuron subtypes using mouse lines and shows their unique roles in motor behavior and anxiety-like behavior through optogenetics and machine learning.

This study identifies that direct-pathway striatal projection neurons (dSPNs) target Npas1+ neurons in the external globus pallidus (GPe) and show that this projection suppresses movement, contributing to Parkinson's disease hypokinesia.

This study identifies distinct roles of PV+ and Npas1+ neurons in the GPe for locomotion and shows differences in their synaptic inputs from the STN in Parkinson's disease.

The paper identifies Npas1+-Nkx2.1+ neurons as a distinct subclass of GPe neurons and describes their role in the cortico-pallido-cortical loop.
