[Effect of increasing demands on the analytic-synthetic activity of the brains of cats on self-regulation of behavior].

In experiments on cats by the method of motor alimentary conditioned reflexes and delayed reactions, their behaviour was studied in response to an unfavourable combination of a certain amount of information subject to analysis and synthesis, of the time assigned for this brain activity, and of a high motivation level. In such conditions, one or all of the following changes of behaviour took place: the time of approaching the feeding-trough increased, a stereotype response to conditioned stimuli with random reinforcement appeared, the level of alimentary motivation was lowered, which was manifested in partial refusals to take food. All these reactions are considered as a reflection of self-regulating brain activity aimed at preventing experimental neurosis.
