title: Presynaptic excitability decrease in the extensor group II afferent terminations.
abstract: The excitability of the extensor secondary afferent terminals is decreased by volleys applied to the flexor group II afferents. This presynaptic excitability decrease was completely abolished after bicuculline, indicating GABA may act as transmitter in this circuit.
