Abstract(in English) | In this paper, we proposed a computational model about how stochastic action selection is realized in the output nuclei of the basal ganglia, more specifically, substantia nigra pars reticulata(SNr) and internal globus pallidus(Gpi). In order to verify our model, we simulated a firing rate model of action selection given stochastic rewards. Our model could acquire proper actions according to changes in the probability of reward. Furthermore, the simulation suggested that action selection becomes more greedy with an increased activity of the subthalamic nuclei. |
