Neuroimage 32:1804-14. 2006..This context also prompted increased activity in the posterior parietal cortex and lateral prefrontal cortex that we attribute to enhanced alertness and sustained attention during unpredictability...
- Emotional perception modulated by an opioid and a cholecystokinin agonistKatarina Gospic
MR Centre, Department of Clinical Neuroscience, Karolinska Institutet, N 8, Karolinska University Hospital, 17176 Stockholm, Sweden
Psychopharmacology (Berl) 197:295-307. 2008..In this behavioral study, we generalize this idea and suggest that CCK and opioids can modulate the processing of other external signals, e.g., visual stimuli rather than only noxious input...
- A regression analysis study of the primary somatosensory cortex during painPredrag Petrovic
PET, Cognitive Neurophysiology, Department of Clinical Neuroscience, Multidisciplinary Pain Center, Department of Rehabilitation Medicine, Karolinska Institute, Karolinska Hospital, Sweden
Neuroimage 16:1142-50. 2002..The results indicate that the S1-cortex may be engaged in or affected by the processing of pain although no differential activity is observed when pain is compared with the reference condition...

Neuron 46:957-69. 2005..Thus, the placebo effect may be considered to be a general process of modulation induced by the subjects' expectations...
- Limbic justice--amygdala involvement in immediate rejection in the Ultimatum GameKatarina Gospic
MR Research Center and Osher Center for Integrative Medicine, Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden
PLoS Biol 9:e1001054. 2011..Our results also prompt an ethical discussion as we demonstrated that a commonly used drug influences core functions in the human brain that underlie individual autonomy and economic decision making...
- Altruism costs-the cheap signal from amygdalaKatarina Gospic
MR Research Center and Osher Center for Integrative Medicine, Department of Clinical Neuroscience, Karolinska Institute, Retzius vag 8, 17177 Stockholm, KTH Royal Institute of Technology, Department of Transport Science, Teknikringen 10, 100 44 Stockholm and VTI, Transport Economics Unit, PO Box 920, 781 29 Borlänge, Sweden
Soc Cogn Affect Neurosci 9:1325-32. 2014..Our findings imply that the emotional system has an important role in real decision making as it signals what kind of immediate cost and reward an outcome is associated with. ..
- Executive functions predict the success of top-soccer playersTorbjörn Vestberg
Department of Clinical Neuroscience, Karolinska Institutet Stockholm, Stockholm, Sweden
PLoS ONE 7:e34731. 2012..The results from this study strongly suggest that results in cognitive function tests predict the success of ball sport players...

Wellcome Trust Centre for Neuroimaging, Institute of Neurology, University College London, 12 Queen Square, London WC1N3BG, UK
Neuron 59:561-7. 2008..We conclude that, even without conscious processing of contextual cues, our brain can learn their reward value and use them to provide a bias on decision making...
- When fear is near: threat imminence elicits prefrontal-periaqueductal gray shifts in humansDean Mobbs
Wellcome Trust Centre for Neuroimaging, Functional Imaging Laboratory, University College London, London WC1N 3BG, UK

- Oxytocin attenuates affective evaluations of conditioned faces and amygdala activityPredrag Petrovic
Wellcome Trust Functional Imaging Laboratory, University College London, London WC1N 3BG, United Kingdom
J Neurosci 28:6607-15. 2008..The data suggest that oxytocin modulates the expression of evaluative conditioning for socially relevant faces via influences on amygdala and fusiform gyrus, an effect that may explain its prosocial effects...
