Definition
Often considered to be the fifth lobe of the brain, the insular lobe lies deep within the Silvian fissure where it is concealed by the frontal, parietal, and temporal lobes. While the function of the insular lobe is not fully understood, it receives nociceptive and visceral sensory input and has been implicated in a variety of processes, ranging from autonomic control, taste perception, and pain processing to subjective emotional experience. Functional neuroimaging studies have also linked the insular lobe to conscious desires, cravings, and addiction as well as a variety of neuropsychiatric disorders, including schizophrenia, mood, panic, posttraumatic stress, and obsessive compulsive disorders.
