Summary
Our intention was to determine the stages of formation of higher nervous tone, and to study the mechanism and its regulation in relation to the ecological and biological significance of continuously applied stimuli; the results were interpreted from the standpoint of comparative physiology.
The experiments were carried out on cats kept under varying lighting conditions. The results showed that the conditioned reflex tonic reactions of the higher nervous centres were formed gradually, and that environmental conditions played an important part in regulating higher nervous tone.
