[The neuronal impulse activity of the subepicardial plexus in the isolated heart of the cat].
The unit activity recorded in the right atrium plexus of the Langendorff preparation was spontaneously irregular in 20 per cent of the neurons. Hexamethonium abolishes it. The spontaneous activity and vagus-induced discharges were inhibited by adrenaline or by stimulation of the stellate ganglion in nearly 30 per cent of the neurons. Activity of some spontaneously active units depended on the effect of the experimental procedure.
