    Abstract:
    Bioelectrical activity of the somatosensory cortex was studied in the Wistar rats with chronic (1.5-2 months) compression of the infraorbital nerve produced by two partial ligations. In 20% of rats spike-slow wave complex and slow waves were observed. Electrostimulation of the skin on the injured nerve side resulted in a considerable increase in the amplitude of early components of the contralaterally evoked potentials in comparison with the non-injured side stimulation in 75% of rats. A decrease in the evoked potential thresholds on the injured nerve stimulation was shown in both hemispheres. In most of the animals a hypersynchronous late component of the evoked potential was observed.
