The study was carried out on dogs by the secretory-motor method with a two-side reinforcement. Simultaneous and unilateral lesion of the premotor cortex and of the dorsal part of the caudate nucleus head brought about prolonged disturbances of the vegetative components (pulse and respiratory rate) and in the choice of the side of food reinforcement. The change in the magnitude of conditioned salivation, latencies of secretion and motor reaction was temporary, and by the end of the third postoperative period their initial magnitudes were restored. The duration of the disturbances of higher nervous activity depended on the localization and extent of lesion of the caudate nucleus head. Tests were made with chlorpromazine and caffeine before and after the lesion of the brain structures. The tests in the postoperative period revealed latent disturbances in the dog higher nervous activity. It is assumed that the premotor cortex and the dorsal part of the caudate nucleus head are one of the sub-systems involved in the regulation of vegetative, somatic components of unconditioned behaviour and in the analysis of conditioned stimuli.
该研究采用分泌运动法对狗进行双侧强化实验。对运动前皮质和尾状核头部背侧进行同时性和单侧性损伤，导致植物性成分（脉搏和呼吸频率）以及食物强化侧选择出现长期紊乱。条件性唾液分泌量、分泌潜伏期和运动反应的变化是暂时的，术后第三个时期结束时恢复到初始水平。高级神经活动紊乱的持续时间取决于尾状核头部损伤的部位和范围。在脑结构损伤前后分别用氯丙嗪和咖啡因进行测试。术后测试揭示了狗高级神经活动中的潜在紊乱。据推测，运动前皮质和尾状核头部背侧是参与调节非条件行为的植物性和躯体性成分以及分析条件刺激的子系统之一。
