Role of the insula in top–down processing: an intracranial EEG study using a visual oddball detection paradigm

Functional neuroimaging studies suggest that the insular cortex—and more especially the anterior insula (aI)—is involved in attentional processes and plays a crucial role in the “salience network”. However, its specific role in attentional processing remains unclear, which is partly attributable to the low temporal resolution of non-invasive neuroimaging techniques. This study aims to examine the spatio-temporal dynamics of visual target...
