Further, theta oscillations across frontoparietal electrodes were also modulated by proactive control demands, with increased theta phase synchrony and power for cues signaling the need for goal updating. Finally, we present novel evidence of negative associations between behavioral variability and both power and phase synchrony across many of these frontoparietal electrodes that were associated with the need for goal updating. In particular, greater consistency in frontoparietal theta oscillations, indicated by increased theta phase and power during mixed-task blocks, resulted in more consistent task-switching performance. Together, these findings provide new insight into the temporal dynamics and functional relevance of theta oscillations during proactive cognitive control.]]> Wed 04 Sep 2019 09:39:54 AEST ]]> Age-related decline in task switching is linked to both global and tract-specific changes in white matter microstructure https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24681 Tue 01 May 2018 15:44:50 AEST ]]>
