The procedure can improve cerebral circulation and thus might also affect cognitive functioning. Magnetoencephalography (MEG) provides a method to gain insight on how the operation affects the electrical mechanisms of the brain related to cognition. Previous research is inconclusive regarding the effects of CEA on cognitive functioning. The neural mechanisms of attention and working memory related to CEA have not previously been studied with MEG. In this study we examine whether carotid endarterectomy affects the neural basis of working memory and attention with MEG. We analyze event-related fields (ERFs) from three different measurement sessions after the operation (n=5). Our study is exploratory and provides insight into what aspects should be considered in future studies. The results of our study do not indicate that the operation has clear effects on the neural correlates of attention and working memory. We did find indications that the operation affects the electrical activity of the brain related to attention, but the meaning of these changes is unclear. The conclusion of our study is that future research should utilize functional brain imaging methods together with cognitive performance evaluation to better understand the effects on cognition. The side of the operated carotid should also be taken into account.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-09-10T05:58:32Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-09-10T05:58:32Z (GMT).
