[The effect of removal of the frontal region of the brain on conditioned reflexes to time and available stimuli].
The experiments were made on six dogs by the motor alimentary technique. It has been shown that ablation of the frontal lobe (fields: F1; F2; F3; F4) does not eliminate previously elaborated conditioned reflexes to time, temporal differentiations and reversals. They were disturbed because of motor perseverance only during the first one to three months. A conditioned reflex to time and temporal differentiations are elaborated much slower in dogs with a preliminary lobectomy, as compared with intact animals. A conclusion is drawn that the frontal lobe is not directly involved in counting the time macrointervals.
