We segmented the EEG in the wait time delay of trials into microstates and categorized the original time series according to the global microstate topographies.
These same microstates were also implicated in the maintenance of attention over short and long timescales, with their time-varying dynamics changing systematically during the wait time delay of trials and over the course of the task session.
My lab has been using a new behavioral task paradigm, first developed by the Engle lab, to investigate sustained attention, mind wandering, and "attention span", independent of changes occurring over the course of task sessions (i.e., time-on-task).

Excited to share a new preprint from my lab at the University of Kentucky looking at the activity and dynamics of EEG microstates during the maintenance of attention over short and long timescales. biorxiv.org/content/10.6...
