title: [A coherence analysis of the electrical activity of the rabbit brain in a thirst dominant].
abstract: Study of the spatial-temporal relations of the brain electrical activity at the dominant of thirst revealed a definite reconstruction of electrical processes' interrelations in the cortex and subcortex in a low-frequency range. Regular increase of coherence level in the delta-range took place between the potentials of the frontal cortical area and APL, AHA, PV testifying to a formation of a primary dominant focus in these structures. At tonic state of the dominant the greatest increase of coherence function evaluations took place in the theta 1-range; before summation movement maximal values of coherence were observed in the theta 2-range. The above-mentioned differences are probably connected with the different levels of motivational-emotional excitation, appearing at corresponding stages of a dominant manifestation.
