Furthermore, olfaction's direct cortical projection enables precise exploration of insular function, promising insights into cognitive and emotional processes. This multifaceted approach will deepen our understanding of the insular cortex and its significance in human cognition and emotion....
An oval region found in each hemisphere of the cerebral cortex, lateral to the lentiform nucleus and situated within the sylvian fissure, involved in sensation, emotion, and autonomic function. Also calledisland of Reil. [New Latinīnsula, from Latin,island.] ...
Sample photomicrographs showing the cytoarchitecture of the insular cortex in humans and in laboratory animals (macaque monkey, domestic cat, and C57BL6 mouse) are presented in Fig.2. In most primates, the insula is a distinct lobe lying in the depth of the sylvian fissure, enclosed by the ...

NIRS measures in pain and analgesia: Fundamentals, features, and function 3.2.7 Insular cortex The insular cortex has at least two subdivisions: anterior and posterior components. It is involved in attention switching and sensory and emotional processing, including evaluating the salience of external ...
These roles are directly relevant to prominent theories of insula function that have emphasized different roles for subregions of the insular cortex in the central representation of interoceptive sensations. For example, the agranular anterior insula has been typically postulated as a region that '...

Anticipation involves preparatory resource allocation to optimize upcoming responses, linked to insular cortex function. Although major depressive disorder (MDD) shows impairments in anticipatory processing and blunted insula activation, it is unclear whether this pattern holds across MDD with and without com...
Compared with other areas of the forebrain, the function of insular cortex is poorly understood. This study examined the unisensory and multisensory function of the rat insula using high-resolution, whole-hemisphere, epipial evoked potential mapping. We found the posterior insula to contain distinct...
Vestibular functionAutonomic functionThe forebrain cerebral network including the insular cortex plays a crucial role in the regulation of the central autonomic nervous system in relation to emotional stress. Numerous studies have recently shown that the insular cortex also has roles as a vestibular area...
