[Evoked potentials of the parafascicular complex of the rabbit thalamus during peripheral painful stimulation].

A systematic investigation of evoked potentials in the parafascicular complex of the thalamic nonspecific system has been carried out on rabbits. Two types of the evoked potentials were recorded due to the electrical skin stimulation of the paw. In the lateral part of the complex several fluctuations consisting of early and late positive-negative potentials following one another were recorded, in the medial--a simple positive-negative evoked potential. A more complex organization of the thalamic parafascicular complex of rodents is suggested.
