[The frontal-motor interneuronal interactions in cats realizing a free choice of reinforcement]

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.
