Area of Science:

  • Neuroimaging
  • Cognitive Neuroscience
  • Systems Neuroscience

Background:

  • Functional connectivity (FC) analysis is commonly used to study brain activity during resting-state and task conditions.
  • FC dynamics, the temporal evolution of connectivity within scans, are increasingly investigated during various cognitive tasks.

Purpose of the Study:

  • To review empirical observations of how functional connectivity differs between task and rest states.
  • To discuss the relationship between instantaneous FC and subsequent perception/performance.
  • To examine the exploration and prediction of mental states using task-concurrent FC dynamics.

Main Methods:

  • Review of empirical observations from functional neuroimaging studies.
  • Analysis of research reports on task-concurrent functional connectivity dynamics.
  • Synthesis of findings on the relationship between FC and behavior.

Main Results:

  • Brain's functional connectivity reconfigures systematically to accommodate task demands, despite overall network preservation.
  • Instantaneous FC is related to perception and performance in subsequent trials.
  • Task-concurrent FC dynamics can be utilized to predict ongoing mental states.

Conclusions:

  • Task-concurrent functional connectivity dynamics are relevant to behavior when properly characterized.
  • The translational value of studying FC dynamics during tasks is considerable.
  • Further research is needed to address challenges in this vibrant area.
