Subthalamic Nucleus Neurons In Progressive Supranuclear Palsy is a cell type relevant to neurodegenerative disease research. This page covers its role in brain function, involvement in disease processes, and significance for therapeutic strategies.
The subthalamic nucleus (STN) is a small, lens-shaped structure located in the diencephalon that plays a critical role in the indirect pathway of the basal ganglia. It serves as the major excitatory driver of the globus pallidus internus (GPi) and substantia nigra pars reticulata (SNr). In progressive supranuclear palsy (PSP), STN neurons are affected by tau pathology, contributing to the characteristic motor dysfunction.
The STN is situated:
STN neurons function as:
The STN acts as a "kernel" in the basal ganglia, with its activity influenced by both inhibitory GPe input and excitatory cortical inputs via the hyperdirect pathway.
The STN is prominently affected in PSP:
The STN has connections to the superior colliculus and brainstem ocular motor nuclei, contributing to:
