| Research Abstract |
To understand neural mechanisms of decision making, we recorded neuronal activity from the prefrontal cortex and basal ganglia of monkeys while animals performed an inference task. While neurons in the basal ganglia couldn't infer more than what monkeys had directly experienced, the prefrontal neurons could infer the relation of events without experience through connecting experienced associations internally. Furthermore, we found such dual neural processes in the human brain by means of fMRI experiments.
