Rusinov V.S. The dominant focus (1969)

   The formation of locus of excitation by the use of polarization with  weak  anodal direct current  of  rabbit's  motor cortex  (for left front limb).

А - absence of motor response on the application photic stimulation before polarization with direct current;

Б -  beginning of motor response of left front limb on the during combined application photic stimulation and polarization with direct current (1.5 μA);

1,2,3 - EEG;

4 - EMG of left front limb;

5 - EMG of right front limb;

6 - EMG of left rear limb;

7 - EMG of right front limb;

bottom line - photic stimulation (8/s).
