The insular cortex is a cytoarchitectonically complex and richly connected structure that functions as a cortical hub involved in interoception, multimodal sensory processing, autonomic control, perceptual self-awareness, and emotional guidance of social behavior.

What is the function of the insular cortex?

The insular cortex links sensory experience and emotional valence. In addition to sensory signals from within the body, the insula receives sensory information from the environment.

Where is the insular cortex?

The insular cortex is located deep within the lateral sulcus of the brain. Also known as the “Island of Reil” based on its initial discovery by Johann Chrstian Reil in 1809, the insula is a region of cortex not visible from the surface view.
