[Cooperative neuronal activity of the n. accumbens and the frontal cortex in cats trained to choose stimuli of various value].
It was shown that the two-way interaction between neurons of the frontal cortex and n. accumbens progressively increases, whereas their regularity simultaneously decreases with the rise in impulsiveness and drop in self-control in behavior. In case of the long-latency instrumental reactions, a control of the frontal cortex neurons by neurons of the n. accumbens weakens during presentation of conditioned stimuli only in "impulsive" animals, which is correlated with low network activity of the n. accumbens. Comparison of patterns of fronto-accumbal interactions during performance of the same type of activity revealed similar correlations in the neuronal pairs before and during presentation of conditioned stimuli, whereas different patterns corresponded to different types of activity.
