Separate neural processes for retrieval of voice identity and word content in working memory

Kristiina Relander, Pia Rämä
2009 Brain Research  
Working memory for voice identity and words was studied to investigate whether the neural system underlying extralinguistic and linguistic information processing is dissociated and whether the possible differences in the distribution of activity are related to specific periods of working memory tasks. Separate analyses of task-related activations evoked during the encoding, maintenance, and recognition periods of the memory tasks were performed. During the voice task, the superior temporal,

Direct contrasts between different periods of the tasks indicated that the ventral prefrontal cortex and the right superior temporal sulcus/gyrus were more activated during recognition than encoding and maintenance periods in the voice compared with the word task. In contrast, the right supramarginal gyrus was more active during the recognition than encoding period in the word compared with the voice task. The results suggest that dissociable neural substrates are recruited for processing of linguistic and extralinguistic information during the recognition period of a working memory task.

BackgroundStenosing atherosclerosis in both coronary and carotid arteries can adversely affect cognition. Also their surgical treatments, coronary artery bypass grafting (CABG) and carotid endarterectomy (CEA), are associated with cognitive changes, but the mechanisms of cognitive decline or improvement may not be the same. This study was designed to compare the cognitive profile and outcome in patients undergoing surgical treatment for coronary or carotid disease.MethodsA total of 100 CABG

They were subjected to a comprehensive neuropsychological examination prior to surgery and in the acute (3–8 days) and stable (3 months) phase after operation. A group of 17 matched healthy controls were assessed with similar intervals. We used linear mixed models to compare cognitive trajectories within six functional domains between the CABG, CEA and control groups. Postoperative cognitive dysfunction (POCD) and improvement (POCI) were determined with the reliable change index method in comparison with healthy controls.ResultsBefore surgery, the CEA patients performed worse than CABG patients or healthy controls in the domains of executive functioning and processing speed. The CABG patients exhibited postoperative cognitive dysfunction more often than the CEA patients in most cognitive domains in the acute phase but had regained their performance in the stable phase. The CEA patients showed more marked postoperative improvement in executive functioning than the CABG group in the acute phase, but the difference did not reach significance in the stable phase.ConclusionOur findings suggest that anterior cerebral dysfunction in CEA patients impairs preoperative cognition more severely than global brain dysfunction in CABG patients. However, CEA may have more beneficial effects on cognition than CABG, specifically in executive functions mainly operated by the prefrontal lobes. In addition, the results underline that POCD is a heterogeneous condition and dependent on type of revascularization surgery.
