[The spectral-correlational analysis of the electrical activity of the rabbit brain in the organization of a goal-directed blinking reaction ].
At organization of the blinking reaction directed to a cessation of the motivational hunger dominant the spectral power of biopotentials of the frontal, sensorimotor cortical areas and the blinking cortical centres of both eyes, VMH and LH increases in the range of the delta- and theta-frequencies. Coherence (Coh) of electrical activity of the frontal and sensorimotor cortical areas increases, Coh between potentials of the swallowing cortical area and the blinking cortical zones corresponding to the trained and non-trained eyes is being asymmetrically reconstructed. Coh function of the electrical activity of the LH, VMH and potentials of different cortical areas changes uniformly. Coh of electrical activity of the VMH and LH, NIII and MPO increases in the whole analysed frequency range, Coh between potentials of the MPO and LPO, LPO and VMH increases in the delta- and decreases in the theta- and alpha-frequency ranges. It is suggested that in the process of preparation of the goal-directed reaction all the cerebral cortex areas and subcortical structures under study related to alimentary motivation and the blinking function are involved into the dominant constellation.
