The cognitive model mainly consists of cerebellum, basal ganglia and cerebral cortex. Thereinto, the cerebellum realizes sensorimotor nerve mapping from states to actions by super- vised learning; the basal ganglia implements probabilistic choice of actions based on operant conditioning principle according to action forecast evaluation results; moreover, the cerebral cortex receives and sends useful information to the basal ganglia and cerebellum, consequently, the closed feedback loop of a sensorimotor system is formed. This paper presents concrete structure, function and algorithm of the sensorimotor system cognitive model based on operant conditioning principle, and perf
