We introduce a decision model that interprets the relative levels of moment-by-moment spiking activity from the right and left superior colliculus to distinguish relevant from irrelevant stimulus events. The model explains detection performance in a covert attention task, both in intact animals and when performance is perturbed by causal manipulations. This provides a specific example of how midbrain activity could support perceptual judgments during attention tasks.
我们引入了一个决策模型，该模型解释了来自右侧和左侧上丘的逐点尖峰活动的相对水平，以区分相关和不相关的刺激事件。该模型解释了在隐蔽注意任务中的检测性能，无论是在完整动物中还是在通过因果操作干扰性能时。这为中脑活动如何在注意任务期间支持知觉判断提供了一个具体的例子。
