The insular cortex (also insula and insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes) within each hemisphere of the mammalian brain.

2024年11月5日 · Insular lobe (lateral-left view) The insula is a lobe that has a triangular shape. It is surrounded by the anterior, superior and medial limiting sulci that are used to distinguish the three parts of the operculum: The frontal operculum …

岛叶 （Insula）是 大脑皮质 的一部分。 它是向内凹陷的皮层区域，被包埋在 外侧裂 之内，无法直接从完整的脑的外部观察到。 它与 额叶， 颞叶 和 顶叶 的皮层相连通。 额叶， 颞叶 和 顶叶 在面向外侧裂，与岛叶相邻的部分叫做“ 岛盖 ”（Operculum）。

Here we provide a concise summary of known structural and functional features of the human insular cortex with a focus on lesion case studies and recent neuroimaging evidence for considerable functional heterogeneity of this brain region. The insular cortex is located deep within the lateral sulcus of the brain.

2022年8月11日 · The insular cortex, or the insula, lies deep to the lateral surface of the brain, completely covered by the frontal, parietal, and temporal opercula. It accounts for approximately 2% of the cortical surface.

Supported by recent human neuroimaging studies, the insula is re-emerging as an important brain area not only in the physiological understanding of the brain, but also in pathological contexts in clinical research. Here, we briefly introduce the anatomical …

2023年5月1日 · The insular cortex (i.e., insula, Latin for "island") is a still poorly understood and hidden structure located deep in the human brain. This telencephalic lobe makes up only about 2% of the complete cortical surface area but is part of complex neural circuitry involving the higher cortex, limbic structures, basal ganglia, and autonomic system.

The insula is the fifth lobe of the brain and it is the least known. Hidden under the temporal, frontal and parietal opercula, as well as under dense arterial and venous vessels, its accessibility is particularly restricted. Functional data on this ...

2017年6月19日 · The insular cortex is a highly associative brain region involved in the processing of feelings and emotions, and in guiding flexible behaviors. In this Primer, Nadine Gogolla describes basic motifs of insula functions and suggests that the rodent model may provide a powerful tool to study the basic neuronal underpinnings of this complex brain ...

2022年7月7日 · The insula brain, perhaps more commonly known as the insular cortex, makes up part of the cerebral cortex. It is found deep in the lateral sulcus of the brain, making it invisible on the surface level.
