The nature of post-stimulation inhibition of the frog lymphatic center was compared with characteristics of a primary inhibition of lymphatic center in spinal and bulbar frogs as well as in a preparation of the isolated spinal cord. The inhibitory mechanism under study seems to involve specific neuron-activators. The activity of the latter provides a certain threshold level of the excitability of the lymphatic center's pace-maker.

In the frog isolated spinal cord, the main parameters of spike activity of the lymphatic center's motoneurons were studied in normal conditions and in altered rhythm of their functioning. Artificial excitation of the lymphatic center by means of stimulation of the dorsal roots, irrespective of the electrical stimuli rate (within the range 1-5 Hz), was shown to induce the same regularities of the evoked motor activity generation in the lymphatic center in the altered rhythm, as in the spontaneous activity of the motoneurons. The main parameters of the evoked activity of motoneurons under these conditions are not significantly dissimilar to the respective parameters of spontaneous activity, either.
