Abstract
THERE is now much experimental evidence supporting the postulate that excitatory and inhibitory synaptic actions are effective by the potential changes that are set up across the motoneurone membrane1,2, the excitatory post-synaptic potential and the inhibitory post-synaptic potential being respectively in the depolarizing and hyperpolarizing directions. When, generated by a virtually synchronous synaptic bombardment, these potential changes are approximately mirror images, the brief rising phases being followed by slower decays (Fig. Aa, b).
