Abstract

The insula is a complex brain region central to the orchestration of taste perception, interoception, emotion, and decision-making. Recent research has shed light on the intricate connections between the insula and other brain regions, revealing the crucial role of this area in integrating sensory, emotional, and cognitive information. The unique anatomical position and extensive connectivity allow the insula to serve as a critical hub in the functional network of the brain. We summarize its role in interoceptive and exteroceptive sensory processing, illustrating insular function as a bridge connecting internal and external experiences. Drawing on recent research, we delineate the insular involvement in emotional processes, highlighting its implications in psychiatric conditions, such as anxiety, depression, and addiction. We further discuss the insular contributions to cognition, focusing on its significant roles in time perception and decision-making. Collectively, the evidence underscores the insular function as a dynamic interface that synthesizes diverse inputs into coherent subjective experiences and decision-making processes. Through this review, we hope to highlight the importance of the insula as an interface between sensation, emotion, and cognition, and to inspire further research into this fascinating brain region.

岛叶皮层:感觉、情感和认知之间的界面
脑岛是一个复杂的脑区,是协调味觉、内感知、情感和决策的核心。最新研究揭示了脑岛与其他脑区之间错综复杂的联系,揭示了该区域在整合感官、情感和认知信息方面的关键作用。独特的解剖位置和广泛的连接性使脑岛成为大脑功能网络中的关键枢纽。我们总结了它在内部感觉和外部感觉处理中的作用,说明了岛叶作为连接内部和外部经验的桥梁的功能。根据最新研究,我们描述了岛叶在情绪过程中的参与,强调了它对焦虑、抑郁和成瘾等精神疾病的影响。我们进一步讨论了岛叶对认知的贡献,重点关注它在时间感知和决策中的重要作用。总之,这些证据强调了岛叶作为一个动态界面的功能,它能将各种输入综合为连贯的主观体验和决策过程。通过这篇综述,我们希望强调岛叶作为感觉、情感和认知之间界面的重要性,并激发对这一迷人脑区的进一步研究。

期刊介绍: Neuroscience Bulletin (NB), the official journal of the Chinese Neuroscience Society, is published monthly by Shanghai Institutes for Biological Sciences (SIBS), Chinese Academy of Sciences (CAS) and Springer. NB aims to publish research advances in the field of neuroscience and promote exchange of scientific ideas within the community. The journal publishes original papers on various topics in neuroscience and focuses on potential disease implications on the nervous system. NB welcomes research contributions on molecular, cellular, or developmental neuroscience using multidisciplinary approaches and functional strategies. We feature full-length original articles, reviews, methods, letters to the editor, insights, and research highlights. As the official journal of the Chinese Neuroscience Society, which currently has more than 12,000 members in China, NB is devoted to facilitating communications between Chinese neuroscientists and their international colleagues. The journal is recognized as the most influential publication in neuroscience research in China.
