The functional neuroanatomy of human working memory revisited

Oliver Gruber, D.Yves von Cramon
2003 NeuroImage  
The results of this study indicate (1) a domain-specific functional-neuroanatomical organization of verbal and visuospatial working memory, (2) a dual architecture of verbal working memory in contrast  ...  In the present event-related functional magnetic resonance imaging study, the neural implementation of human working memory was reinvestigated using a factorial design with verbal and visuospatial item-recognition  ...  Prior to this study, four functional imaging studies have compared verbal and visuospatial working memory within the same subjects.  ...

Resting state signatures of domain and demand-specific working memory performance

Wessel O. van Dam, Scott L. Decker, Jeffery S. Durbin, Jennifer M.C. Vendemia, Rutvik H. Desai
2015 NeuroImage  
Working memory (WM) is one of the key constructs in understanding higher-level cognition.  ...  Furthermore, verbal and visuospatial memory capacities were associated with dissociable patterns of low-frequency fluctuations.  ...  These results show a dissociation of STM and WM measures in the parietal cortex, with more inferior regions predicting STM performance and more superior regions reflective of the more demanding WM measure  ...

The role of inferior parietal and inferior frontal cortex in working memory

Juliana V. Baldo, Nina F. Dronkers
2006 Neuropsychology  
In the current study, the authors tested two groups of patients who were chosen on the basis of their relatively focal lesions in the inferior parietal (IP) cortex or inferior frontal (IF) cortex.  ...  These findings lend further support to the working memory model and provide evidence of the roles of IP and IF cortex in separable working memory processes.  ...  Another discrepancy in the neuroimaging literature has been the exact locus of verbal working memory within parietal cortex (Becker et al., 1999; Ravizza, Delgado, Chein, Becker, & Fiez, 2004) .  ...

Learning and memory: recent findings

Peter Bright, Michael D. Kopelman
2001 Current Opinion in Neurology  
Further work must address the complex dynamics of the memory system, the extent to which the same regions underlie different functions, and how different regions interact and reflect common functions.  ...  This has implications, both for existing models of memory function, and in the methodology of future investigations and the issues they address.  ...  Dissociation of different components of verbal shortterm memory was demonstrated in a functional MRI study by Henson et al. [5 . ].  ...
