Spinal Reticulospinal Neurons are projection neurons that originate in the brainstem reticular formation and descend to the spinal cord to coordinate posture, locomotion, autonomic functions, and pain modulation. These neurons form a critical descending pathway that integrates brainstem commands with spinal motor circuits.

Reticulospinal neurons arise from two main regions of the reticular formation:
Reticulospinal neurons coordinate multiple motor and autonomic systems:
Reticulospinal neurons use glutamate as their primary excitatory neurotransmitter, acting through AMPA and NMDA receptors. They also contain:
The study of Spinal Reticulospinal Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
