Curiosity is often portrayed as a desirable feature of human faculty. However, curiosity may come at a cost that sometimes puts people in harmful situations. Here, using a set of behavioural and neuroimaging experiments with stimuli that strongly trigger curiosity (for example, magic tricks), we examine the psychological and neural mechanisms underlying the motivational effect of curiosity. We consistently demonstrate that across different samples, people are indeed willing to gamble, subjecting themselves to electric shocks to satisfy their curiosity for trivial knowledge that carries no apparent instrumental value. Also, this influence of curiosity shares common neural mechanisms with that of hunger for food. In particular, we show that acceptance (compared to rejection) of curiosity-driven or incentive-driven gambles is accompanied by enhanced activity in the ventral striatum when curiosity or hunger was elicited, which extends into the dorsal striatum when participants made a decision.

共同的纹状体活动，以决定满足好奇和饥饿的危险，并有触电的危险。

好奇心经常被描绘成人类教师的理想特征。但是，好奇心可能要付出代价，有时甚至使人们处于有害的境地。在这里，我们使用一组行为和神经影像实验，对刺激强烈激发好奇心（例如魔术）的刺激进行了研究，我们研究了激发好奇心的心理和神经机制。我们始终如一地证明，在不同的样本中，人们确实愿意赌博，遭受电击，以满足对无明显工具价值的琐碎知识的好奇心。同样，这种好奇心的影响与食物饥饿有着共同的神经机制。尤其是，
