Role of theĀ Insular Cortex in Emotional Awareness

Island of Reil (Insula) in the Human Brain

Abstract

New studies keep drawing attention to the role of the insular cortex in emotional awareness. Emotional awareness is necessary to achieve and maintain mental health and social well-being. This chapter discusses the existing theories on emotional awareness and its correlation with interoception, the sense of the inner body. Emotional awareness and interoception have been shown to be two inseparable concepts. Several brain regions are involved in orchestrating the neural circuitry of emotional awareness (e.g., anterior cingulate cortex, amygdala); however, the insular cortex is the maestro. Furthermore, although anterior insular cortex and anterior cingulate cortex are coactivated, studies have shown they are potentially functionally separable. Insular lesions may cause impairments in emotional awareness, known as alexithymia.
