- •
The intrinsic functional organization of the human working memory remains unknown, we hypothesize that it is an energy-efficient system.
- •
We tested this hypothesis by analyzing associations between WM performance at different task difficulties and the FCD and FCS in 282 young adults.
- •
These findings suggest that the intrinsic working memory network is an energy-efficient and hierarchical system.
