In our previous studies, we investigated the relationship between performance and anatomic connectivity and found that this relation was not necessarily the same for different reading groups (i.e., DRs, TRs).
We investigated the modulatory effects of regional brain atrophy, indexed by structural measures of disease load, on the relationship between performance and brain activity (or connectivity) using task-based and resting-state functional MRI.
Figure 2 B demonstrates the relationship between performance and inward versus outward connectivity differences for both TRs and DRs. This relationship is significant for DRs (r5 = 0.96, P < 0.001) but not TRs (r8 = 0.40, P > 0.10).
Mobile Performance and Connectivity.
The distinction is between performance and welfare.
Striking Balance Between Performance and Energy Consumption.
We then employed DTI to examine the relationship between expert performance and structural connectivity in the brain.
In all these regions, the correlations between global cognitive performance and functional connectivity that demonstrated increased slope with structural disease load suggest a compensatory effect in the right hemisphere in preHD.
However, there were definite differences in the relationship between task performance and the effective connectivity between the left TPA and other brain areas.
