Earlier studies with functional imaging in schizophrenia have demonstrated dysfunction of the dorsolateral prefrontal cortex during working memory. Controlling for behavioral performance and for catechol-O-methyltransferase (COMT) Val158Met genotype, we here demonstrate in a functional magnetic resonance imaging paradigm that patients recruit greater(More)

To prove this hypothesis, “dimensional diagnosis”, based on the identification of a(More)

Several studies have investigated the clinical and epidemiological features of OCS/OCD in SCZ, but the neuroimaging literature is(More)
