2020 biorxiv/medrxiv   pre-print
Previous research has shown that the coordinated activity between (i.e., functional connectivity, 'inter-FC') cingulo-opercular (COn) and right-frontoparietal (RFPn) networks is linked to visual processing  ...  We found that visual processing speed was negatively associated with inter-FC between RFPn and visual networks in Slow-5 and Slow-2, with no corresponding significant association for inter-FC between COn  ...  Archila-Meléndez for helpful feedback on an earlier version of this paper and Dr Julia Neitzel for participant recruitment.  ...

Neural correlates of establishing, maintaining, and switching brain states

Yi-Yuan Tang, Mary K. Rothbart, Michael I. Posner
2012 Trends in Cognitive Sciences  
In this review, we summarize recent research on three relatively well-described brain states: the resting, alert, and meditation states.  ...  Although the study of brain states is an old one in neuroscience, there has been growing interest in brain state specification owing to MRI studies tracing brain connectivity at rest.  ...  Acknowledgements We would like to thank Rongxiang Tang for assistance with artwork on all figures.  ...

The developing brain in a multitasking world

Mary K. Rothbart, Michael I. Posner
2015 Developmental Review  
In this paper we discuss the development of brain networks related to the functions of achieving the alert state, orienting to sensory events, and developing selfcontrol.  ...  Playing action video games and multitasking are themselves methods of training the brain that can lead to improved performance but also to overdependence on media activity.  ...  Acknowledgments The authors acknowledge support from NICHD grant HD 060563. We also acknowledge the important ideas of Professor Yi-Yuan Tang that helped to shape our paper.  ...
