Vagus Preganglionic [Neurons](/entities/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.
Vagus preganglionic neurons are parasympathetic motor neurons located primarily in the dorsal motor nucleus of the vagus (DMV) in the medulla oblongata. These neurons provide parasympathetic innervation to visceral organs, controlling heart rate, digestion, respiratory rate, and other essential autonomic functions. They are increasingly recognized as affected in [Parkinson's disease](/diseases/parkinsons-disease-disease) and other neurodegenerative disorders. [@flores2022]

Overview
Mermaid diagram (expand to render)
Vagus preganglionic neurons represent the efferent component of the vagus nerve, carrying parasympathetic signals from the brainstem to thoracic and abdominal viscera. They are part of the enteric brain axis and play critical roles in gut-brain communication. [@braak2003]
Key Characteristics
Location: Dorsal motor nucleus of the vagus (DMV), nucleus ambiguus (NA)
