Abstract

After bilateral ablation of prefrontal and premotor areas of the brain in dogs, considerable changes of the "spontaneous" and unconditioned activity occurred: the phenomenon of squeezing through narrow spaces, the reflex of resistance against restriction of movements, the disturbances of sexual reflexes, the feigned aggression, etc. These reflex actions acquire features of the dominant. Seeking for food, when carrying out instrumental conditioned reflexes, also manifests features of the dominant. The pathological dominant is suggested to be a result of disorder in normal interrelationship between the excitatory and inhibitory processes. It occurs when a disruption of the process of inner inhibition takes place in the system, while the excitatory process becomes extremely powerful. This entails those motor perseverations, hyperactivity, imitational movements, and all the analysed disturbances of reflex activity in dogs after frontal lobectomy.
