Globus Pallidus Internal Segment (Gpi) Gabaergic Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Globus Pallidus Internal Segment (GPi) is the main output nucleus of the basal ganglia. Its GABAergic neurons provide inhibitory projections to thalamic and brainstem motor centers, critically influencing movement execution. [1]
The GPi receives input from both the direct and indirect pathways and serves as the principal inhibitory output of the basal ganglia. It tonically inhibits thalamocortical and brainstem motor circuits. [2]
