During tasks requiring focused attention, regions specialized to the tasks at hand became active in the subjects whose brains were being scanned.
During tasks, starting 30 s before scanning, participants listened to pacing cues generated by a metronome.
Importantly, and most relevant to our hypothesis, is the work of Barnes and colleagues5 and He and colleagues6,7 who demonstrated that the Hurst exponent is highest during rest, and decreases during tasks.
In this study of the relationship between sensory processing and cardiovascular function, 5 cardiovascular parameters were monitored during baseline periods and during tasks requiring either sensory intake or sensory rejection behavior on the part of 19 subjects.
In the same study29, the IFS network was particularly active during tasks that required more complex cognitive processes, for example, reasoning, planning and mental rotation.
Conversely, the ARP model proposes that the AIFO and IFS are involved during tasks that tax attention and that involve processing novel or complex rules, respectively.
That is, the movements of the hands may be coupled during tasks in which temporal and spatial synchronizations are beneficial for performance.
Ten university students typed on a keyboard, moved and clicked a mouse during tasks under various preset and self-selected speeds for 3 min.
Moreover, we replicated our previous finding that ATD modulated the BOLD response in the dorsomedial prefrontal cortex during tasks that require cognitive control.
PMd has been implicated in the planing and execution of voluntary movements (PMd), and the majority of its cells are active during tasks with instructed delay time.
Hypotheses were stated within Baddeley and Hitch's (1974) multicomponent model of VSTM, with respect to regions of the brain known to be active during tasks tapping into VSTM.
