Associations evoked during memory encoding recruit the context-networkJan Peters
Department of Neuropsychology, Institute of Cognitive Neuroscience, Ruhr University of Bochum, Germany
Hippocampus 19:141-51. 2009..Our data suggest that the context network, which includes the posterior hippocampus and parahippocampal cortex, might support the linkage of external stimuli to long-term memory representations...- Impairment of verbal recollection following ischemic damage to the right anterior hippocampusJan Peters
Department of Neuropsychology, Ruhr University of Bochum, Germany
Cortex 45:592-601. 2009.... - Overlapping and distinct neural systems code for subjective value during intertemporal and risky decision makingJan Peters
NeuroImage Nord, Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, D 20246 Hamburg, Germany
J Neurosci 29:15727-34. 2009..These results suggest a mechanism for the neural coding of subjective value in the human brain that is based on the combination of domain-general and domain-specific valuation networks... - Risk taking and the adolescent reward system: a potential common link to substance abuseSophia Schneider
University Medical Center Hamburg Eppendorf, Hamburg, Germany
Am J Psychiatry 169:39-46. 2012..g., the ventral striatum) to nondrug reward cues has been reported in addiction. One unanswered question is whether risk-taking preference is associated with striatal reward processing in the absence of substance abuse... - Sleep deprivation is associated with attenuated parametric valuation and control signals in the midbrain during value-based decision makingMareike M Menz
NeuroimageNord, Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, D 20246 Hamburg, Germany
J Neurosci 32:6937-46. 2012..Conflict-related midbrain signals showed a similar downregulation. Findings are discussed with respect to changes in dopaminergic signaling associated with the sleep-deprived state... - Direct evidence for domain-sensitive functional subregions in human entorhinal cortexHeidrun Schultz
Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, 20246 Hamburg, Germany
J Neurosci 32:4716-23. 2012..Our data thus provide direct evidence for a functional specialization within human entorhinal cortex and thereby strongly support MTL models that emphasize the importance of partially segregated parallel processing streams... - Don't look back in anger! Responsiveness to missed chances in successful and nonsuccessful agingStefanie Brassen
Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, Hamburg, Germany
Science 336:612-4. 2012..Our results suggest that disengagement from regret reflects a critical resilience factor for emotional health in older age... - The neural mechanisms of inter-temporal decision-making: understanding variabilityJan Peters
Department of Systems Neuroscience, University Medical Centre Hamburg Eppendorf, Martinistrase 52, 20246 Hamburg, Germany
Trends Cogn Sci 15:227-39. 2011..Although the precise neural mechanisms underlying many of these modulating influences are only beginning to be unravelled, they point towards novel treatment approaches for disorders of impulse control... 
Domain-specific retrieval of source information in the medial temporal lobeJan Peters
International Graduate School of Neuroscience, Ruhr University of Bochum, Germany
Eur J Neurosci 26:1333-43. 2007..Results are discussed with respect to anatomical models of corticoparahippocampal connectivity and the functional organization of the MTL...- Domain-specific impairment of source memory following a right posterior medial temporal lobe lesionJan Peters
International Graduate School of Neuroscience, Ruhr University of Bochum, Germany
Hippocampus 17:505-9. 2007..The findings are in good agreement with the view of dissociable memory processing by the perirhinal cortex (anterior MTL) and parahippocampal cortex (posterior MTL), depending upon the neocortical input that these regions receive... - Episodic future thinking reduces reward delay discounting through an enhancement of prefrontal-mediotemporal interactionsJan Peters
NeuroimageNord, Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, Hamburg, Germany
Neuron 66:138-48. 2010..The present data reveal a mechanism through which neural decision-making and prospection networks can interact to generate future-minded choice behavior... - Structure-function relationships in the processing of regret in the orbitofrontal cortexTobias Sommer
Department of Systems Neuroscience, NeuroImage Nord, University of Hamburg Medical School, Bldg S10, Hamburg, Germany
Brain Struct Funct 213:535-51. 2009..Vice versa, the differential contribution of OFC subregions to these processes also adds evidence to the current debate on the function of this cortical structure in decision-making that attracted increasing attention in recent years... - Differential effects of normal aging on recollection of concrete and abstract wordsJan Peters
Institute of Cognitive Neuroscience, Department of Neuropsychology, Ruhr University of Bochum, Germany
Neuropsychology 22:255-61. 2008..These findings are consistent with the idea that changes in hippocampally mediated recollective processes during aging affect concrete words more than abstract words... - Frontal but not parietal positivity during source recollection is sensitive to episodic contentJan Peters
Institute of Cognitive Neuroscience, Department of Neuropsychology, Ruhr University Bochum, Germany
Neurosci Lett 454:182-6. 2009..Our findings confirm and extend previous observations by showing that, when recollection is assessed using an objective performance measure (i.e., source accuracy), frontal brain potentials are sensitive to episodic content... - Altered neural reward representations in pathological gamblers revealed by delay and probability discountingStephan F Miedl
Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, Hamburg, Germany
Arch Gen Psychiatry 69:177-86. 2012..The neural basis of excessive delay discounting and reduced risk sensitivity of pathological gamblers with a particular focus on subjective neural reward representations has not been previously examined... - Lower ventral striatal activation during reward anticipation in adolescent smokersJan Peters
Department of Systems Neuroscience, Universitaetsklinikum Hamburg Eppendorf, Germany
Am J Psychiatry 168:540-9. 2011..Adolescents are particularly vulnerable to addiction, and in the case of smoking, this often leads to long-lasting nicotine dependence. The authors investigated a possible neural mechanism underlying this vulnerability... 
Formal comparison of dual-parameter temporal discounting models in controls and pathological gamblersJan Peters
NeuroimageNord, Department of Systems Neuroscience, University Medical Center Hamburg Eppendorf, Hamburg, Germany
PLoS ONE 7:e47225. 2012..The CS model may be a useful tool in future psychiatry, psychology and neuroscience work on inter-temporal choice...
