Insular volumetry in severe alcohol use disorder and Korsakoff's syndrome through an anatomical parcellation: Let us go back to basics

Pauline Billaux,

et al.

Abstract: Functional neuroimaging has demonstrated the key role played by the insula in severe alcohol use disorder (sAUD), notably through its involvement in craving and body signals processing. However, the anatomical counterpart of these functional modifications in sAUD patients with and without neurological complications remains largely unexplored, especially using state‐of‐the‐art parcellation tools. We thus compared the grey matter volume of insular subregions (form anterior to posterior: anterior inferior cortex,… Show more

“… 24 , 25 , 26 , 27 , 28 The insula has emerged as a primary neural hub in these dynamic interplays between limbic and prefrontal systems. Specifically, the (anterior) insula integrates autonomic and visceral signals into reward‐motivational functions, 29 , 30 which could modulate the balance between the impulsive and reflective neural systems when facing reward‐related cues. 10 , 11 , 31 Accordingly, we have no a priori hypotheses regarding the directionality of the pattern of insular‐based connectivity (i.e., either positive or negative PPI).…”
