Abstract text:	Obsessive-compulsive disorder (OCD) is characterized by repetitive thoughts and behaviors associated with underlying dysregulation of frontostriatal circuitry. Central to neurobiological models of OCD is the orbitofrontal cortex, a neural region that facilitates behavioral flexibility after negative feedback (reversal learning). We identified abnormally reduced activation of several cortical regions, including the lateral orbitofrontal cortex, during reversal learning in OCD patients and their clinically unaffected close relatives, supporting the existence of an underlying previously undiscovered endophenotype for this disorder.

The Reprint Request service is currently unavailable. The webform interface is not passing on your requests despite saying it has. PDF's of articles are also not available unless specifically linked from the record under the link field. Open Access papers are accessible this way when available. We are not able to fulfill pdf requests due to copyright and contractual restrictions. Inclusion in the Bibliography does not mean that a copy is available, this is foremost a record of the unit's work. Papers marked 'In Press' have not been published so are not available. Books and tests are also not available for copying. These are commerical products and you will need to buy them, or indeed contact your local library service to get a copy. If a record is from a conference and does not show more than one page number then the record/abstract on the page is the complete record. These are mainly a record of participation in a conference, such as a poster or a talk. Some of these records represent literally nothing more than a line.
