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.
摘要:
脑岛是一个复杂的大脑区域,是味觉感知编排的核心,相互感受,情感,和决策。最近的研究揭示了脑岛和其他大脑区域之间的复杂联系,揭示了该区域在整合感觉中的关键作用,情感,和认知信息。独特的解剖位置和广泛的连通性允许脑岛作为大脑功能网络的关键枢纽。我们总结了它在交互感受和外感受感觉加工中的作用,说明岛礁作为连接内部和外部经验的桥梁。根据最近的研究,我们描绘了孤立地参与情感过程,强调它对精神病的影响,比如焦虑,抑郁症,和上瘾。我们进一步讨论了岛屿对认知的贡献,专注于其在时间感知和决策中的重要作用。总的来说,证据强调了岛屿作为动态界面的功能,可将各种输入合成为连贯的主观经验和决策过程。通过这次审查,我们希望强调脑岛作为感觉之间接口的重要性,情感,和认知,并激发对这个迷人大脑区域的进一步研究。
