The amplitude, time course and charge of unitary excitatory post-synaptic potentials evoked in spinal motoneurone dendrites

摘要

1. Group Ia e.p.s.p.s were recorded from lumbosacral motoneurones in anaesthetized cats after almost complete section of the appropriate dorsal roots. The cable parameters of these same motoneurones were obtained from the voltage response to a brief intracellular current pulse, as described in Iansek & Redman (1973).
