Ventral Respiratory Group Expanded is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The ventral respiratory group (VRG) is a bilateral column of neurons located in the ventrolateral medulla that controls respiratory muscle activity. It is the primary respiratory rhythm generator for expiration and contributes to inspiration through coordinated neural circuits[^1].
The VRG extends from the level of the obex to the C1 spinal segment. It is organized into three subdivisions:
Key nuclei within the VRG include:
The VRG contains the core respiratory rhythm generators:
VRG neurons project to:
VRG neurons are severely affected in ALS:
VRG dysfunction in PD contributes to:
Autonomic failure in MSA includes:
