原始语种摘要: Abstract(#br)Decision making involves the allocation of cognitive resources in response to expectations and feedback. Here we explored how frontal networks respond in a gambling paradigm in which uncertainty was manipulated to increase demands for cognitive control. In one experiment, pupil diameter covaried with uncertainty during decision making and with the degree to which subsequent outcomes violated reward expectations. In a second experiment, fMRI showed that both uncertainty and unexpected outcomes modulated activation in a network of frontal regions. Thus, the frontal network supports multiple phases of the decision-making process including information regarding reward uncertainty and reward outcome. In contrast, striatal activation only tracked reward delivery, suggesting a...
