I guess that is right. Some reductionists, however, think that biology is the fundamental level. If it doesn't target biology then there is little point to it.

References -- certainly, the doctors have moved on since to private practice as well, but you can see some of the old images herehttp://hope4ocd.com/overview.php
http://www.brainmattersinc.com/ocd.html
These have no references attached but I can say that I have seen these many times. The color images are probably in more older journals such asBrain imaging as a tool in establishing a theory of brain pathology in obsessive compulsive disorder.
J Clin Psychiatry. 1990 Feb;51 Suppl:22-5; discussion 26.J Clin Psychiatry. 1994 Oct;55 Suppl:54-9. Links
Positron emission tomography studies of cerebral glucose metabolism in obsessive compulsive disorder.* Baxter LR Jr.
Department of Psychiatry and Biobehavioral Sciences.
"In the last 7 years, positron emission tomography (PET) scanning studies of obsessive compulsive disorder have given us new insights into misfunctionings of brain systems that may mediate the symptomatic expression of this classical "neurosis." Work by several PET groups indicates that a prefrontal cortex-basal ganglia-thalamic circuit may be the brain pathway leading to the broken record patterns of obsessions and compulsions."
And ongoing research continues

So while I can't put an old glossy Grand Rounds or journal link here, there are many references to PET scans of OCD pointing at the caudate nucleus.-- J
