Response inhibition and interference control in obsessive-compulsive spectrum disorders

Abstract

Over the past 20 years, motor response inhibition and interference control have received considerable scientific effort and attention, due to their important role in behavior and the development of neuropsychiatric disorders. Results of neuroimaging studies indicate that motor response inhibition and interference control are dependent on cortical-striatal-thalamic-cortical (CSTC) circuits. Structural and functional abnormalities within the CSTC circuits have been reported for many neuropsychiatric disorders, including obsessive-compulsive disorder (OCD) and related disorders, such as attention-deficit hyperactivity disorder, Tourette's syndrome, and trichotillomania. These disorders also sha..
