Response Patterns of Vestibulospinal Neurons to Lumbar Rotation in Decerebrate Rats
Jpn J Physiol Vol.54, No.5 pp.495-498
Abstract: In vestibulospinal neurons projecting to the lumbar enlargement, activities were modulated in response to alternate tilts of the caudal body around the vertebral axis. Three types of neurons were found: Type I (37.8%) showed faster firing during the ipsilateral side-down tilt; type II (51.1%) showed the reverse pattern; type III were unaffected. Types I and II may be important in the tonic lumbar reflex.
