A region of the brain deep in the cerebral cortex.
- ‘The areas most affected were the superior temporal, anterior insula, and orbitofrontal cortices.’
- ‘The insular cortex is indented by a number of sulci, one of which - the central sulcus of the insula - is deeper and more prominent than the rest.’
- ‘A few seconds later, presumably as the person responded to the humor, brain regions called the insula and amygdala became active across both hemispheres of the brain.’
- ‘While rejecting an offer, increased brain activity was observed in the anterior insula, which is associated with negative emotions such as disgust.’
- ‘The insula relays messages between imitation and emotion regions, Iacoboni suggests.’
Mid 19th century: Latin, literally island.
