Local and distributed neural networks and individuality.

The functional organization of local and distributed neural networks was studied in cats with different individual typological features of voluntary behavior. Stable behavioral characteristics were assessed using an individually varying selection of a larger (better) food reinforcement depending on the delay time in the operant motor response. Judging from the organization of interneuronal interactions, the decisive role in producing the choice of response is played by influences from hypothalamic and amygdalar motivational structures on the anterior parts of the neocortex, which was typical of rapidly-responding ("impulsive") cats, and interactions between frontal cortex and hippocampal systems in animals which delayed pedal pressing to receive the preferred food, i.e., animals with "self control."
