There has been a tendency to investigate phenomena in vivo from the standpoint of the self-organizing system. According to this postulation, the order of the living body is established by the relationship between the parts and the whole with their mutual feed-back loops. The equilibrium system consists of two parts, peripheral equilibrium organs and their centers, and these two are closely connected by their feedback loops. Thus, the characteristics of the equilibrium system seem to be similar to those of the self-organizing system.
In this paper, the following subjects are discussed from the standpoint of the self-organizing system.
1. Coordination and competition between the optic organ and the labyrinth with regard to the maintenance of body equilibrium.
2. Physiology of training of the optic organ and the labyrinth, and mutual transfer of effects of training of these two organs.
3. The characteristics of centripetal and centrifugal parts of the labyrinthine system.
4. The characteristics of exchange of information between the upper and the lower parts of the brain relevant to the maintenance of body equilibrium.
The results of the above examinations suggest that the idea of the self-organizing system is an aid to the understanding of the characteristics of various phenomena with regard to the maintenance of body equilibrium.
