Lateralization of the Insular Cortex
The insula functions primarily to integrate interoceptive and viscerosensory input. These functions are lateralized and can broadly be separated into positive or negative emotional valence, approach or avoidance behaviors, perception or experience of a certain phenomenon, as well as conscious perception of one’s own affective state. This also includes monitoring of autonomic functions, emotional and cognitive processing, and a role in language production. Further studies are needed to clearly demarcate boundaries in persons differing in gender, handedness, or a possible psychiatric disorder.
