White, Stuart F.; Brislin, Sarah; Sinclair, Stephen; Fowler, Katherine A.; Pope, Kayla; Blair, R. James R. – Journal of Child Psychology and Psychiatry, 2013
Background: The presence of a large cavum septum pellucidum (CSP) has been previously associated with antisocial behavior/psychopathic traits in an adult community sample. Aims: The current study investigated the relationship between a large CSP and symptom severity in disruptive behavior disorders (DBD; conduct disorder and oppositional defiant…

Cavanagh, James F.; Grundler, Theo O. J.; Frank, Michael J.; Allen, John J. B. – Neuropsychologia, 2010
Larger error-related negativities (ERNs) have been consistently found in obsessive-compulsive disorder (OCD) patients, and are thought to reflect the activities of a hyperactive cortico-striatal circuit during action monitoring. We previously observed that obsessive-compulsive (OC) symptomatic students (non-patients) have larger ERNs during errors…

Peer reviewed Peer reviewed

Ursu, Stefan; Carter, Cameron S. – Neuropsychologia, 2009
Orbitofrontal cortical (OFC) dysfunction has been repeatedly involved in obsessive-compulsive disorder, but the precise significance of this abnormality is still unclear. Current neurocognitive models propose that specific areas of the OFC contribute to behavioral regulation by representing the anticipated affective value of future events. This…
