[The cortico-hypothalamic relations of the electrical activity in a motor polarization dominant].
By means of spectral-correlation analysis was studied the dynamics of the structural changes of coherent relations of the electrical activity of the sensorimotor cortex and the medical hypothalamus (MH) of the rabbit under motor polarization dominant created by the action of DC anode on the sensorimotor cortex area. During the motor dominant the spectral power of MH activity was shown to increase in the delta-band. The structural changes of coherent relations of the electrical activity of the sensorimotor cortex and the MH were manifested by a decrease of coherence in the delta- and alpha-frequency bands. Electrical stimulation of the MH inhibited the motor dominant reactions.
