Division of Psychological Medicine and Psychiatry, King s College London Institute of Psychiatry, London, UK
J Psychopharmacol 25:722-33. 2011..Our results suggest that networks implicated in the allocation of attentional resources (VMPFC) and emotion processing (amygdala, cerebellum) are differentially affected in patients on CONV versus RLAI...

Inserm U930 ERL, Université François Rabelais and CHRU de Tours, Tours, France
Neuroimage 76:90-7. 2013..The novelty of our results lies in the demonstration of gene by sex interaction with resting blood flow in the amygdala that elucidates sex-related differences in emotional reactivity...

Institute of Psychiatry, De Crespigny Park, London SE5 8AF, UK
Br J Psychiatry 193:222-8. 2008..Depersonalisation disorder is characterised by emotion suppression, but the cerebral mechanisms of this symptom are not yet fully understood...
- The effect of long-acting risperidone on working memory in schizophrenia: a functional magnetic resonance imaging studySimon A Surguladze
Department of Psychiatry, King s College London Institute of Psychiatry, De Crespigny Park, London, UK
J Clin Psychopharmacol 27:560-70. 2007..We conclude that RLAI may contribute to normalization of brain activation in regions involved in working memory functioning in people with chronic schizophrenia...

Section of Neuroscience and Emotion, Division of Psychological Medicine, Institute of Psychiatry, King s College London, London, United Kingdom
Neuropsychology 18:212-8. 2004..The authors suggest that, in depressed patients, the inability to accurately identify subtle changes in facial expression displayed by others in social situations may underlie the impaired interpersonal functioning...
- A preferential increase in the extrastriate response to signals of dangerSimon A Surguladze
Section of Neuroscience and Emotion, Division of Psychological Medicine, Institute of Psychiatry, De Crespigny Park, London SE5 8AF, UK
Neuroimage 19:1317-28. 2003..We suggest that this differential pattern of response to different categories of emotional signals allows the preferential direction of visual attention to signals of imminent danger than to other, less-salient emotional stimuli...
