Institut d Alta Tecnologia Parc de Recerca Biomèdica de Barcelona, Centro Radiológico Computerizado, Barcelona, Spain
Arch Gen Psychiatry 69:741-9. 2012..Recent advances in social cognitive neuroscience suggest that a compelling relationship may exist between this disorder-relevant processing bias and the functional activity of brain regions implicated in OCD...
- Evaluating brain activity in obsessive-compulsive disorder: preliminary insights from a multivariate analysisBen J Harrison
Melbourne Neuropsychiatry Centre, Department of Psychiatry, The University of Melbourne, Melbourne, Victoria, Australia

- Task-induced deactivation from rest extends beyond the default mode brain networkBen J Harrison
Institut d Alta Tecnologia PRBB, CRC MAR, Hospital del Mar, Barcelona, Spain
PLoS ONE 6:e22964. 2011..Together, these findings suggest that task-induced deactivations from rest are not limited to the DMN and extend to brain regions typically associated with integrative sensory and interoceptive processes...
- Altered corticostriatal functional connectivity in obsessive-compulsive disorderBen J Harrison
Institut d Alta Tecnologia Parc de Recerca Biomèdica de Barcelona, Centro Radiológico Computerizado Corporació Sanitària, Barcelona, Spain
Arch Gen Psychiatry 66:1189-200. 2009..Although neuroimaging studies of patients have supported this network model of OCD, very few have applied measurements that are sensitive to brain connectivity features...
- Consistency and functional specialization in the default mode brain networkBen J Harrison
Institut d Alta Tecnologia Parc de Recerca Biomèdica de Barcelona, CRC Corporació Sanitària, 08003 Barcelona, Spain
Proc Natl Acad Sci U S A 105:9781-6. 2008..Mapping spontaneous and task-related brain activity will help to constrain the meaning of the default mode network. These findings are discussed in relation to recent debate on the topic of default modes of brain function...
- Modulation of brain resting-state networks by sad mood inductionBen J Harrison
Melbourne Neuropsychiatry Centre, Department of Psychiatry, The University of Melbourne and Melbourne Health, Victoria, Australia
PLoS ONE 3:e1794. 2008..While these 'resting-state networks' may be relatively enduring phenomena, other evidence suggest that dynamic changes in their functional connectivity may also emerge depending on the brain state of subjects during scanning...

Melbourne Neuropsychiatry Centre, Department of Psychiatry, The University of Melbourne, Australia
Schizophr Res 91:82-6. 2007..The nature of these associations suggests a complex interchange between cognitive and emotional influences on the resting-state activity of these prefrontal 'default mode' regions in schizophrenia...
