The idea that predictions shape how we perceive and comprehend the world has become increasingly influential in the field of systems neuroscience. It also forms an important framework for understanding neuropsychiatric disorders, which are proposed to be the result of disturbances in the mechanisms through which prior information influences perception and belief, leading to the production of suboptimal models of the world. There is a widespread tendency to conceptualize the influence of predictions exclusively in terms of 'top-down' processes, whereby predictions generated in higher-level areas exert their influence on lower-level areas within an information processing hierarchy. However, this excludes from consideration the predictive information embedded in the 'bottom-up' stream of information processing. We describe evidence for the importance of this distinction and argue that it is critical for the development of the predictive processing framework and, ultimately, for an understanding of the perturbations that drive the emergence of neuropsychiatric symptoms and experiences.

神经系统中的预测形式。

预测塑造我们如何感知和理解世界的想法在系统神经科学领域变得越来越有影响力。它还构成了理解神经精神疾病的重要框架，神经精神疾病被认为是先验信息影响感知和信念的机制紊乱的结果，导致世界次优模型的产生。有一种普遍的趋势，即仅根据“自上而下”过程来概念化预测的影响，即在较高级别区域中生成的预测会对信息处理层次结构中的较低级别区域产生影响。然而，这排除了嵌入在“自下而上”信息处理流中的预测信息。
