目标导向和刺激驱动的因素分别通过一个明确的背侧额顶叶和腹侧颞顶叶脑区网络来决定注意优先级。最近的证据表明，奖励相关的刺激也有高的注意优先级，独立于他们的身体显着性和目标相关性。这种价值驱动的注意力控制背后的神经机制尚不清楚。使用人类功能磁共振成像，我们证明尾状核和纹外视皮层的尾部优先响应任务无关，但以前奖励相关的对象，提供了一个注意力优先信号，是敏感的奖励历史。尾状尾并不参与目标导向或刺激驱动的注意力控制，但非常适合调解价值驱动的注意力控制。我们的研究结果揭示了基于价值的注意优先的神经基础。
Goal-directed and stimulus-driven factors determine attentional priority through a well defined dorsal frontal-parietal and ventral temporal-parietal network of brain regions, respectively. Recent evidence demonstrates that reward-related stimuli also have high attentional priority, independent of their physical salience and goal-relevance. The neural mechanisms underlying such value-driven attentional control are unknown. Using human functional magnetic resonance imaging, we demonstrate that the tail of the caudate nucleus and extrastriate visual cortex respond preferentially to task-irrelevant but previously reward-associated objects, providing an attentional priority signal that is sensitive to reward history. The caudate tail has not been implicated in the control of goal-directed or stimulus-driven attention, but is well suited to mediate the value-driven control of attention. Our findings reveal the neural basis of value-based attentional priority.
