Instrumental delayed reflexes with reinforcement of different quality were elaborated in six cats by the method of "active choice", where the time of delay of the motor reaction served as a signal of quality of the reinforcement. Individually varying ability to choose the quality of the reinforcement was used for classification of typological features of cats (self-control and impulsiveness). Multiunit activity was recorded by nichrome semimicroelectrodes from the frontal and motor cortical areas. Crosscorrelation analysis of interneuronal connections was carried out. The interneuronal frontal-motor relationships with different temporal delays (0-30; 30-60; 60-100 ms) were equally manifested in both groups of cats. We suggested that the organization of the frontal-motor relations did not characterize the individual typological features of the cats. During short-delayed reflexes in cats of both groups the identified functional connections with delays 0-30 ms were more significant. The question is discussed on the role of the frontal-motor coordination in definition of the kind of behaviour of cats to fulfil either short- or long-delayed conditioned reactions.
通过“主动选择”方法，在六只猫身上建立了具有不同强化性质的工具性延迟反射，其中运动反应的延迟时间作为强化性质的信号。利用个体对强化性质选择能力的差异对猫的类型特征（自我控制和冲动性）进行分类。用镍铬合金半微电极记录额叶和运动皮层区域的多单位活动。进行了神经元间连接的互相关分析。两组猫中，不同时间延迟（0 - 30；30 - 60；60 - 100毫秒）的神经元额叶 - 运动关系均有同等程度的表现。我们认为额叶 - 运动关系的组织并不能表征猫的个体类型特征。在两组猫的短延迟反射过程中，确定的延迟0 - 30毫秒的功能连接更为显著。文中讨论了额叶 - 运动协调在确定猫执行短期或长期延迟条件反应行为类型中的作用问题。
