摘要

Individuals with obsessive-compulsive disorder (OCD) often report urges preceding their compulsions. Although the insula has a key role in interoception and prior work in OCD showed increased neural activity during the build-up of an urge using an eyeblink-suppression task, little is known about insula connectivity during urge-suppression in OCD.
