High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Summary

Brain dynamics underlying attention fluctuations were explored using fMRI. Dynamic transitions between brain states, particularly involving the dorsal attention and default mode networks, correlate with changes in sustained attention performance.

Area of Science:

Neuroscience
Cognitive Science
Psychology

Background:

Maintaining sustained attention is crucial for task performance.
Attentional levels naturally fluctuate during daily activities.
The brain mechanisms driving these attentional fluctuations remain largely unknown.

Purpose of the Study:

To investigate the neural dynamics associated with sustained attention.
To understand the brain mechanisms underlying attentional fluctuations during a task.

Main Methods:

Functional magnetic resonance imaging (fMRI) was employed.
Participants performed an auditory, gradual-onset, continuous performance task (gradCPT).
Event-related analysis and energy landscape analysis were utilized.

Main Results:

Frontal and temporal areas, including the auditory cortex, showed activation during response inhibition.
Reaction time variability positively correlated with activity in the dorsal attention network (superior frontal gyrus, superior parietal lobule).
Task-related brain activations clustered into distinct attractors within the dorsal attention and default mode networks.

Conclusions:

Dynamic transitions between brain states are closely linked to fluctuations in auditory attention.
Increased alternations between stable and erratic performance periods corresponded with greater transitions between brain network attractors.
