The pulvinar nucleus of the thalamus is a crucial component of the visual system and plays significant roles in sensory processing and cognitive integration. The pulvinar’s extensive connectivity with cortical regions allows for bidirectional communication, contributing to the integration of sensory information across the visual hierarchy. Recent findings underscore the pulvinar’s involvement in attentional modulation, feature binding, and predictive coding. In this review, we highlight recent advances in clarifying the pulvinar’s circuitry and function. We discuss the contributions of the pulvinar to signal modulation across the global cortical network and place these findings within theoretical frameworks of cortical processing, particularly the global neuronal workspace (GNW) theory and predictive coding.

丘脑的枕核是视觉系统的重要组成部分，在感觉处理和认知整合中发挥着重要作用。枕丘与皮质区域的广泛连接允许双向通信，有助于跨视觉层次的感觉信息的整合。最近的研究结果强调了 pulvinar 参与注意力调节、特征绑定和预测编码。在这篇综述中，我们重点介绍了在阐明枕丘电路和功能方面的最新进展。我们讨论了枕丘对整个皮质网络信号调制的贡献，并将这些发现置于皮质处理的理论框架中，特别是全局神经元工作空间（GNW）理论和预测编码。
