title: [Interaction of stationary excitation foci in the rabbit brain].
abstract: Influence of "animal hypnosis" on the motor polarization dominanta created by direct anodic current applied on the left sensorimotor cortex of the rabbit ("left" dominanta) was studied in chronic experiments. Animal behavior and electrophysiological characteristics were recorded. It was impossible to elicit the "animal hypnosis" during the optimum of the "left" dominanta. The state of "animal hypnosis" could be easily elicited against the background of the latent focus of the "left" dominanta on the next day after its formation. The "animal hypnosis" restored the "left" dominanta after its extinction. It was accompanied by formation of a new pattern of the cortical EEG coherence in the delta range, which was different from the patterns characteristic of each kind of dominanta. After the "animal hypnosis" session, the formation of the "left" dominanta produced two kinds of nonstable foci. During testing, the "left" dominanta reached its optimum and then inhibited the tonic activity of the right forelimb characteristic of the "animal hypnosis". The interaction of the "animal hypnosis" and the dominant foci in the left and right sensorimotor cortex were different.
