Activity in DNCORE and DNSUB3 increased increased during periods of task-unrelated thought, and internally-oriented thought, while activity in DNMTL increased when deliberate constraints on thought were weak.
For example, the dorsolateral prefrontal cortex (DLPFC) is recruited in a task during periods of task-unrelated-thought (TUT) [15].
These findings complement what is observed in cross-sectional studies of TBI [3], [34], [5] and in healthy adults during periods of high task load [39] [41] whereby increased involvement of neural resources may be highly dependent upon performance and does not represent fundamental changes in the network.
Parieto-occipital alpha power, meanwhile, provides a complementary index of general task preparation, with alpha suppression observed during periods of high cognitive effort and task engagement (Klimesch et al. 2007; Snyder and Foxe 2010; Macdonald et al. 2011).
10.7554/eLife.05360.013 Figure 7. SPW-R-associated modulation of VTA units during periods of quiet wakefulness (QW) on the task and during subsequent slow wave sleep (SWS).
These sessions occurred 3 weeks after the M&M, and since have enabled task shifting during periods of high patient flow, resulting in improved laboratory capacity.
A set of functionally connected brain regions that is involved in spontaneous, internally driven cognitive processes and is more active during periods of rest than during externally driven tasks.
Neuroimaging evidence has identified a network of brain regions that is less metabolically active during goal-oriented tasks than during periods of rest.
Tic frequency did not increase during periods of increased heart rate, and during the public speech task tic frequencies were actually lower during periods of increased heart rate.
To keep yourself focused and engaged, especially during periods of doubt and increased anxiety, keep yourself accountable with a task list.
