这篇前景文章讨论了检测和应对变化或意外事件的神经生物学。变化检测是大脑执行的一项持续的计算任务，作为显着性映射和选择下一个注意目标的更广泛过程的一部分。在仓鸮的视顶盖（OT）中，刺激的概率对神经对该刺激的反应有显着的影响;与普通刺激相比，罕见或异常的刺激会引起更强的反应。这种现象被称为刺激特异性适应，最近引起了科学界的兴趣，因为它可能在变化检测中发挥作用。在仓鸮的OT中，它可能是专门针对意外事件的能力的基础，因此为习惯化，注意力和惊喜等基本心理现象的神经生物学研究开辟了新的方向。
This prospect article addresses the neurobiology of detecting and responding to changes or unexpected events. Change detection is an ongoing computational task performed by the brain as part of the broader process of saliency mapping and selection of the next target for attention. In the optic tectum (OT) of the barn owl, the probability of the stimulus has a dramatic influence on the neural response to that stimulus; rare or deviant stimuli induce stronger responses compared to common stimuli. This phenomenon, known as stimulus-specific adaptation, has recently attracted scientific interest because of its possible role in change detection. In the barn owl's OT, it may underlie the ability to orient specifically to unexpected events and is therefore opening new directions for research on the neurobiology of fundamental psychological phenomena such as habituation, attention, and surprise.
