High trait anxiety and hyporeactivity to stress of the dorsomedial prefrontal cortex: a combined phMRI and Fos study in ratsRaffael Kalisch
NMR Study Group, Max Planck Institute of Psychiatry, Munich, Germany
Neuroimage 23:382-91. 2004..In the context of an anxiety-inhibiting role of the dmPFC, we propose that failure to sufficiently activate this region in stressful situations may contribute to high trait anxiety...

Neurosci Biobehav Rev 33:1215-26. 2009..In agreement with the model, preliminary evidence from parametric meta-analysis suggests the two stages are supported by distinct frontal networks. Hypotheses for further research are presented...
The NMDA agonist D-cycloserine facilitates fear memory consolidation in humansRaffael Kalisch
Functional Imaging Laboratory, Wellcome Department of Imaging Neuroscience, University College London, London, UK
Cereb Cortex 19:187-96. 2009..DCS also enhanced CS-evoked neural responses in a posterior hippocampus/collateral sulcus region and in the medial prefrontal cortex at test. Our data suggest a role for NMDA receptors in regulating fear memory consolidation in humans...
Context-dependent human extinction memory is mediated by a ventromedial prefrontal and hippocampal networkRaffael Kalisch
Wellcome Department of Imaging Neuroscience, Functional Imaging Laboratory, Institute of Neurology, University College London, London, WC1N 3BG, United Kingdom
J Neurosci 26:9503-11. 2006..Thus, a VMPFC-hippocampal network provides for context-dependent recall of human extinction memory, consistent with a view that hippocampus confers context dependence on VMPFC...
Levels of appraisal: a medial prefrontal role in high-level appraisal of emotional materialRaffael Kalisch
Wellcome Department of Imaging Neuroscience, Functional Imaging Laboratory, Institute of Neurology, University College London, London WC1N 3BG, UK
Neuroimage 30:1458-66. 2006..Our data provide neurobiological evidence for a distinction between low-level and high-level appraisal mechanisms...
Learning affective values for faces is expressed in amygdala and fusiform gyrusPredrag Petrovic
Wellcome Trust Centre for Neuroimaging, University College of London, 12 Queen Square, London, WC1N 3BG, UK
Soc Cogn Affect Neurosci 3:109-18. 2008..We conclude that amygdala and fusiform encode affective value in a manner that closely approximates a standard computational solution to learning...
Anterolateral prefrontal cortex mediates the analgesic effect of expected and perceived control over painKatja Wiech
Wellcome Department of Imaging Neuroscience, Institute of Neurology, London WC1N 3BG, United Kingdom
J Neurosci 26:11501-9. 2006..Failure to activate right alPFC may explain the maladaptive effects of strong general control beliefs during uncontrollable pain...
Modulation of pain processing in hyperalgesia by cognitive demandKatja Wiech
Wellcome Department of Imaging Neuroscience, Institute of Neurology, UCL, 12 Queen Square, London WC1N 3BG, UK
Neuroimage 27:59-69. 2005..Within the limitations of an experimental model of pain, we suggest that the findings are relevant to understanding both the neurobiology and pathophysiology of chronic pain and its amelioration by cognitive strategies...
Anxiety reduction through detachment: subjective, physiological, and neural effectsRaffael Kalisch
University College London, UK
J Cogn Neurosci 17:874-83. 2005..Using functional magnetic resonance imaging, we locate the potential site and source of this modulation of anticipatory anxiety in the medial prefrontal/anterior cingulate and anterolateral prefrontal cortex, respectively...
A meta-analysis of instructed fear studies: implications for conscious appraisal of threatMarie Luise Mechias
Institute for Systems Neuroscience and NeuroImage Nord Hamburg Kiel Lübeck, University Medical Center Hamburg Eppendorf UKE, Martinistr 52, 20246 Hamburg, Germany
Neuroimage 49:1760-8. 2010..These data suggest that mid regions of the dmPFC/dACC are part of a "core" fear network that is activated irrespective of how fear was learnt...
