title: [Functional state of the suprasegmental structures of the brain in experimental secondary contracture of the facial muscles].
abstract: For the first time the model of secondary contractures of facial nerves was used to study by long-term sterotaxic implanted electrodes the state of the cortex, amygdal complex, reticular formation of the middle brain, reticular nuclei of the pons and nuclei of the facial nerves. The experiments were accomplished on 31 rabbits. The experiments confirmed a close functional connnection of the VII pair of cranial nerves with the limbico-reticular complex. In secondary contracture there were factors facilitating the influence of pons reticular structures on the deficient system the facial nerve--facial muscles. The achieved data are used to explain the origination of the main symptom of secondary contractures--a stable increase of the muscular tone.
