Abstract
The dynamics of changes in intercentral relations of electrical activity of the sensorimotor and premotor zones of both hemispheres and the ventroposterolateral (VPL) nucleus of the left and right thalamus at formation of motor dominant under the action of the DC anode in the rabbit sensorimotor cortex was studied by the method of spectral-correlation analysis. It is shown that in the dominant motor analyzer (the sensorimotor cortex and VPL) highly coherent connections of electrical processes are formed in the delta-range with conjugated lowering of biopotential connections between the structures of the motor analyzer of the nondominant part of the brain. At the same time differently directed connections of electrical processes are formed between the structures of the motor analyzer, and between the premotor cortex and focus area. Thus, during formation of the polarization dominant, a new structure of the intercentral relations of electrical processes is established not only in the dominant but also in the other half of the brain.
