Deciphering decision making: exploring the interactions between neural and neurochemical systems underlying the evaluation versus employment of cognitive effort in rats

决定我们经济成功与否的大多数关键决策都涉及两种选择，一种是提供较低回报的容易的东西，另一种是如果我们成功了，提供巨大回报的困难的东西。了解我们的大脑如何做出这样的决定是认知和行为神经科学学术学科的主要目标之一。许多有用的信息是通过研究健康志愿者在实验室游戏中的决策而获得的，但通常很难确定观察到的大脑活动和选择模式之间的关系是否表明大脑区域是

Most of the key decisions that determine our economic success involve the choice between something easy that provides lower returns, or something difficult that, should we succeed, provides great reward. Understanding how our brains make such decisions is one of the primary goals of the academic disciplines of cognitive and behavioural neuroscience. A lot of useful information is obtained from studying the decision making of healthy volunteers in laboratory-based games, but it is often hard to determine whether relationships observed between, say, brain activity and choice patterns indicate that a brain region is
