As an integral part of this objective, our group has an important methodological component, the characterization of interactions in spatially distributed neural activity, which is the central topic of this PhD project. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><u><span lang=EN-US>Project Description<o:p></o:p></span></u></p><p class=MsoNormal><span lang=EN-US>Phase-consistent rhythmic activity is ubiquitous in electrophysiological recordings, and it may reflect networks of phase-coupled neuronal populations oscillating at different frequencies. Because neuronal oscillations may reflect rhythmic modulations of neuronal excitability, phase-coupled oscillatory networks (PCONs) could be functional building blocks for routing information through the brain. This project focuses on PCONs involving brain rhythms that (1) are modulated by selective attention and working memory, and (2) are correlated with individual differences in cognitive performance. Using newly developed methods, we extract PCONs from magneto-encephalography (MEG) data on the basis of the patterns of phase-consistency induced by these PCONs. These methods succeed because PCONs can be separated on the basis their frequency content, the brain areas over which they can be observed, and their pattern of between-site phase relations. We will test three hypotheses with respect to the functional role of alpha and theta band PCONs, one pertaining to their behavioral relevance, one to the mechanism underlying sustained attention, and one to their relation with individual differences in cognitive performance. All hypotheses can be tested using existing data.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><u><span lang=EN-US>Job Requirements<o:p></o:p></span></u></p><p class=MsoNormal><span lang=EN-US>This project calls for either a cognitive neuroscientist with a strong interest and skills in data analysis or a person with a computational background (machine learning, applied statistics, signal processing) with a strong interest in cognitive neuroscience.

The Donders Institute focuses on state of the art cognitive neuroscience, in a multidisciplinary approach, and offers excellent lab and neuroimaging facilities. The project is embedded within the Donders research theme <i>Brain Networks and Neuronal Communication</i> (<a href="http://www.ru.nl/donders/research/theme-4-brain/">http://www.ru.nl/donders/research/theme-4-brain/</a>) and will be supervised by dr. Eric Maris at the Donders Centre for Cognition (DCC). The DCC is part of the Faculty of Social Sciences, one of the largest faculties at Radboud University Nijmegen. The faculty hosts high-quality research and study programs that rank among the best in the Netherlands.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><u><span lang=EN-US>Contact Information<o:p></o:p></span></u></p><p class=MsoNormal><span lang=EN-US>Dr. Eric Maris<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><a href="mailto:e.maris@donders.ru.nl">e.maris@donders.ru.nl</a><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
