Striatal Cholinergic Interneurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Striatal cholinergic interneurons (also known as tonically active neurons or TANs) are large, aspiny interneurons in the striatum that release acetylcholine. They play crucial roles in modulating striatal circuitry and are directly affected in Parkinson's disease. [@zhou2002]

Overview
Mermaid diagram (expand to render)
Striatal cholinergic interneurons represent approximately 1-2% of the total striatal neuron population but exert profound influence on basal ganglia function. These cells are characterized by their large cell bodies, extensive dendritic arborizations, and rhythmic firing patterns. They are essential for reward learning, movement selection, and adaptive behaviors.
