预测误差(PE)是强化学习、感知推理、决策和认知的理论模型中的一个核心概念,预测误差信号已经在广泛的大脑区域和实验范式中被报道。在这里,我们将尝试只见树木不见森林,并考虑报告的PE信号的共性和差异,根据最近的建议,PE的计算形成了大脑功能的基本模式。我们讨论不同类型的PE编码,它们是如何产生的,以及它们所履行的不同功能角色。我们认为,虽然PE的编码是跨大脑区域的常见计算,但这些错误信号的内容和功能可能非常不同,并且由它们出现的神经回路内的传入和传出连接决定。
Prediction errors (PE) are a central notion in theoretical models of reinforcement learning, perceptual inference, decision-making and cognition, and prediction error signals have been reported across a wide range of brain regions and experimental paradigms. Here, we will make an attempt to see the forest for the trees and consider the commonalities and differences of reported PE signals in light of recent suggestions that the computation of PE forms a fundamental mode of brain function. We discuss where different types of PE are encoded, how they are generated, and the different functional roles they fulfill. We suggest that while encoding of PE is a common computation across brain regions, the content and function of these error signals can be very different and are determined by the afferent and efferent connections within the neural circuitry in which they arise.
