Figure 2From: Dopamine signals for reward value and risk: basic and recent dataSustained activations related to risk. The risk response occurs during the stimulus-reward interval (arrow) subsequently to the phasic, value related activation to the stimulus (triangle). The inset, top right, shows that risk (ordinate) varies according to an inverted U function of reward probability (abscissa) (Data from previous work [18].Back to article page
