1908 C. S. Sherrington in Proc. Royal Soc. B. 80 55 It is only after withdrawal of that stimulus that the discharge of the extensor motoneurones occurs.
1937 C. H. Best & N. B. Taylor Physiol. Basis Med. Pract. lxv. 1278 Many reflexes gradually increase to a maximum when a stimulus of unaltered intensity is merely prolonged. This is due to the activation of a progressively greater number of motoneurons.
1943 Jrnl. Neurophysiol. 6 311 Few if any extensor motoneurons could have discharged in the earlier reflex.
1964 J. Z. Young Model of Brain iv. 50 In a mammal the largest motoneurons of the spinal cord may have a dendrite spread of 1 m.
1987 M. J. Neal Med. Pharmacol. at Glance xx. 47/1 It is the transmitter released from motoneurone nerve endings at the neuromuscular junction.
2001 Nature Neurosci. 4 1065 Current models suggest that vertebrate motoneuron death results from failure to compete for limited, target-derived trophic support.
