THE SYNAPTIC DELAY OF THE MOTONEURONES

Abstract

The synaptic delay of the motoneurones of N III was measured in a preparation in which no inter-nuncial neurones are present between the excited fibers and the motoneurones and in which errors due to un-known speeds of conduction can not occur. The synaptic delay of the motoneurones measures 0.50-1.36 [sigma] and is roughly in inverse relation to the strength of the stimu-lus (number of activated synapses). The endplate de-lay in the eye muscles measures 0.7 (in normal) to 1.3 a (in cool muscle).
