[Relationship between interhemispheric irradiation of excitation and the individual characteristics of the animal].

The changes in irradiation coefficient (the ratio between the value of secretion resulting from interhemispheric irradiation of secretion and the main one secreted on the side of excitation evaluated in per cent) were studied in norm and under different functional loads in dogs with exposed symmetrical parts of the tongue following the method of K. S. Abuladse. It is shown that dogs with low and mean level of irradiation of excitation have good mobility of nervous processes and rapid excitation in homonomous structures whereas dogs with high coefficient of irradiation demonstrated inert nervous processes and were not able to show a clear one-way reaction during interhemispheric interaction. A group of dogs with sharply pronounced asymmetry in coefficient of irradiation to the right and to the left is described. This description permitted an assumption about functional heterogeneity of the hemispheres. The obtained data showed that the character of interhemispheric irradiation is determined by individual characteristics of animals.
