J Psychiatr Res 47:350-6. 2013..This study sought to compare neural activations in the ventral striatum (VS) and prefrontal regions during reward processing in homogenous ADHD subtype groups and healthy adults, using the MID task...
- Alterations of theory of mind network activation in chronic cannabis usersPatrik Roser
Department of Psychiatry, LWL University Hospital, Ruhr University Bochum, Germany
Schizophr Res 139:19-26. 2012..These activation patterns resemble those found in at-risk populations, suggesting that cannabis use can affect the processing of social information similar to other risk factor constellations for psychosis...

Department of Neurology, BG Kliniken Bergmannsheil, Ruhr University, D 44780 Bochum, Germany
Curr Biol 19:837-42. 2009..These findings suggest that brief periods of reduced use of a limb have overt consequences and thus constitute a significant driving force of brain organization equivalent to enhanced use...

Department of Neurology, BG Kliniken Bergmannsheil, Buerkle de la Camp Platz 1, 44789 Bochum, Germany
J Physiol 584:463-71. 2007..Conceivably, changes of cortical excitability seem to constitute an additional important marker and mechanism underlying plastic reorganization...
- Out of context: NMDA receptor antagonism in the avian 'prefrontal cortex' impairs context processing in a conditional discrimination taskSilke Lissek
Institute for Cognitive Neuroscience, Faculty of Psychology, Department of Biopsychology, Ruhr Universitat Bochum, Bochum, Germany
Behav Neurosci 119:797-805. 2005..Therefore, NMDA receptors in the avian PFC participate in response selection requiring context processing rather than in response selection per se...
- Maintenance in working memory or response selection? Functions of NMDA receptors in the pigeon "prefrontal cortex"Silke Lissek
Department of Biopsychology, Faculty of Psychology, Institute for Cognitive Neuroscience, Ruhr Universitat Bochum, 44780 Bochum, Germany
Behav Brain Res 153:497-506. 2004..We conclude that NMDA receptors in the pigeon NCL participate in response selection rather than stimulus maintenance in tasks requiring the processing of context information...
