Dr Samuel Chamberlain MB/BChir PhD MRCPsych University positionWellcome Trust Fellow, Honorary Consultant Psychiatrist DepartmentsHome pagehttp://www.srchamb.com (personal home page) Research ThemesInterestsNeurobiology and treatment of impulsive, compulsive, and behaviourally-addictive disorders. I use a variety of techniques, including cognitive assessment, brain imaging, and pharmacological challenges, to explore the brain underpinnings of these conditions and the mechanisms through which treatments affect cognition, and improve symptoms.  Brain activation during reversal of responses. Patients with OCD and their unaffected relatives showed under-active brain regions during reversal compared to people with no family history of the condition.
