Structure and Function of the Human Insula

Open access

Abstract

Summary: The insular cortex, or “Island of Reil,” is hidden deep within the lateral sulcus of the brain. Subdivisions within the insula have been identified on the basis of cytoarchitectonics, sulcal landmarks, and connectivity. Depending on the parcellation technique used, the insula can be divided into anywhere between 2 and 13 distinct subdivisions. The insula subserves a wide variety of functions in humans ranging from sensory and affective processing to high-level cognition. 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 insula can be considered as a hub integrating exteroceptive sensory inputs and interoceptive signals, linking external and internal experiences.

    “The insula can be considered as a hub integrating exteroceptive sensory inputs and interoceptive signals (Uddin, Nomi, H ebert-Seropian, Ghaziri, & Boucher, 2017), and linking external and internal experiences.”

    From The Peripersonal Space in a social world (2021) · cites this paper as Uddin et al., 2017

  • The shared anatomical features of the insula across rodents and humans suggest a role in fundamental and evolutionarily conserved functions.

    “many anatomical features of the insula are shared across rodents and humans, suggesting its role in some fundamental and evolutionarily conserved functions [10].”

    From The Insular Cortex: An Interface Between Sensation, Emotion and Cognition (2024) · cites this paper as [10]

    The “Cytoarchitecture, structural and functional connectivity” section compares insular connections in humans and macaques, not rodents. The copy’s summary describes functions of the human insula, but the passages found when searching for rodents and evolutionary conservation do not address shared rodent–human anatomy or infer conserved functions from it. (LLM, conf=0.74)

  • Many anatomical features of the insula are shared across rodents and humans.

    “Although the human insula has a uniquely larger number of gyri and increased volume relative to brain size, many anatomical features of the insula are shared across rodents and humans, suggesting its role in some fundamental and evolutionarily conserved functions [10].”

    From The Insular Cortex: An Interface Between Sensation, Emotion and Cognition (2024) · cites this paper as [10]

    The Cytoarchitecture, structural and functional connectivity section describes similarities in insular connections between humans and macaques, but does not compare humans with rodents. Searches for rodents, rats, mice, and comparative anatomy found no passage establishing the claimed shared features. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
