Carin Whitney, Susanne Weis, Timo Krings, Walter Huber, Murray Grossman, Tilo Kircher
2009 Journal of Cognitive Neuroscience  
Functional imaging studies of single word production have consistently reported activation of the lateral prefrontal and cingulate cortex.  ...  Hippocampal activity during spontaneous word production is a novel finding and seems to be dependent on the retrieval process (free vs. constrained) rather than the variety of stimulus-response relationships  ...  Acknowledgments The study was supported by a grant from the Interdisciplinary Center for Clinical Research "BIOMAT" within the Faculty of Medicine at the RWTH Aachen University (IZKF VV N68) and the International  ...

Furthermore, we argue that the ability to compensate for the effect of cognitive aging depends on the amount of reserve specific to each individual which is, in turn, modulated by the AMF.  ...  AbstractIn the absence of any neuropsychiatric condition, older adults may show declining performance in several cognitive processes and among them, in retrieving and producing words, reflected in slower  ...  In the absence of any specific task, the intrinsic activity is represented by several distinct and distributed functional subnetworks or modules, involving several brain regions which are connected with  ...

Influence of reward motivation on human declarative memory

Ewa A. Miendlarzewska, Daphne Bavelier, Sophie Schwartz

In particular, temporally-correlated activity in the hippocampus and in regions of the dopaminergic circuit may mediate value-based decisions and facilitate cross-item integration.  ...  Existing evidence suggests that the neurotransmitter dopamine boosts the formation of declarative memory for rewarded information and may also control the generalization of reward values.  ...  Acknowledgements This work was supported by the National Center of Competence in Research (NCCR) Affective Sciences financed by the Swiss National Science Foundation (no. 51NF40-104897) and hosted by the  ...
