Department of Psychological Medicine, Institute of Psychiatry, London, England
Biol Psychiatry 58:495-503. 2005..We wished to corroborate these results by examining neural responses to personally relevant happy and sad stimuli in MDD and healthy individuals within the same paradigm...
- The neural correlates of anhedonia in major depressive disorderPaul A Keedwell

- Neural markers of symptomatic improvement during antidepressant therapy in severe depression: subgenual cingulate and visual cortical responses to sad, but not happy, facial stimuli are correlated with changes in symptom scoreP Keedwell
Cardiff University, Psychological Medicine, Cardiff, UK
J Psychopharmacol 23:775-88. 2009..There are contrasting cortical and subcortical responses to sad and happy stimuli in severe depression. Responses to sad stimuli show the strongest correlates of clinical improvement, particularly in the subgenual cingulate...
- Subgenual cingulate and visual cortex responses to sad faces predict clinical outcome during antidepressant treatment for depressionPaul A Keedwell
Department of Psychological Medicine, Cardiff University, Heath Park, Cardiff CF14 4XN, UK
J Affect Disord 120:120-5. 2010..We hypothesized that greater responses in these areas to sad stimuli, but not happy stimuli, would predict better subsequent clinical outcome. We also explored areas that would predict a poor outcome...
- Marked reductions in visual evoked responses but not γ-aminobutyric acid concentrations or γ-band measures in remitted depressionAlexander Shaw
Institute of Neuroscience and Mental Health, MRC Centre for Neuropsychiatric Genetics and Genomics, Henry Wellcome Building, Cardiff University, Heath Park, Cardiff CF14 4XN, United Kingdom
Biol Psychiatry 73:691-8. 2013..In this study we investigated whether γ oscillations and GABA concentrations would differ in individuals with remitted depression (RD) compared with never depressed control subjects (ND)...
