[Influence of sympathetic fiber stimulation on conduction of excitation in the cat pterygopalatine ganglion].
Interaction between excitation passing through parasympathetic and sympathetic pathways was studied by recording of action potentials evoked in postganglionic nerves of the cat pterygopalatine ganglion by both testing stimuli applied to the greater superficial  petrosal nerve and conditioning stimuli applied to cervical sympathetic nerve. Depression of synaptic transmission through the ganglion is shown to take place under stimulation of the cervical sympathetic nerve. The magnitude of such inhibition reached to 13 +/- 3%.
