[Name of Birdsey Renshaw (1911–48), U.S. neurologist, who investigated such cells.]
Renshaw cell: a nerve cell in the spinal cord that is innervated by collaterals from a motor neurone and forms synapses with that and adjacent motor neurones so as to provide an inhibitory feedback path.
1954J. C. Eccles et al. in Jrnl. Physiol. CXXVI. 533 A detailed study of the interneuronal discharges has established that these interneurones form a specialized group mediating the inhibitory path from motor axons. They may appropriately be given the distinguishing title of ‘Renshaw cells’. 1974M. C. Gerald Pharmacol. xv. 277 The Renshaw cells exert an inhibitory influence on the flow of nerve impulses along motor neurons in the spinal cord. 1976W. R. Ingram Rev. Anat. Neurol. i. 23 Some investigators have questioned the validity of the Renshaw cell concept. |
