Аннотация: Experiments were performed on six dogs to study the effects of simultaneous and separate ablation of fields 5 and 7 of the parietal cortex on “counting” behavior. Dogs were trained to discriminate series of five sound clicks presented with variable interstimulus intervals from similar series consisting of three clicks. A food-related operant response (elevation of the right forepaw to place it on the feeder) was used to develop asymmetrical differentiation; the positive signal was a series of five clicks with variable interstimulus intervals and the negative (unreinforced) stimulus was a series of three clicks. Simultaneous bilateral ablation of fields 5 and 7 of the parietal cortex, like bilateral ablation only of field 5, produced profound impairment of differentiation lasting 2–3 months. Isolated bilateral ablation of field 7 produced no impairment of differentiation. These data led to the conclusion that field 5 of the parietal cortex is important for discriminating the numbers of sequential signals.
