Understanding Neural Flexibility From a Multifaceted Definition

Dazhi Yin, Marcus Kaiser
2021 NeuroImage  
This review not only strengthens our understanding of flexible human brain, but also suggests that the measure of neural flexibility could bridge the gap between understanding intrinsic and task-driven  ...  However, flexibility is usually inferred from separate components of brain activity (i.e., intrinsic/task-evoked), and different definitions are used.  ...  We begin with a discussion of brain-wide functional connectivity patterns in the shift between intrinsic and taskevoked states.  ...
