The intercentral relationships of rabbit brain biopotentials during the creation of a blink dominant.
The intercentral relationships of the biopotentials of the sensorimotor area of the cerebral cortex, the ventroposteromedial nucleus of the thalamus, and the motor nucleus of the oculomotor nerve during the formation of a blink dominant, created by means of serial stimulation of one eye by an airstream, were investigated in chronic experiments on rabbits by the spectral correlation analysis method. An increase in the power of the spectrum and an increase in the COH of the potentials of the delta range were identified in structures associated with the function of the blinking of the stimulated eye. Analogous reorganizations of biopotentials were identified in a dominant focus arising by induction of the symmetrical center of the other eye.
