Aging Gracefully: Compensatory Brain Activity in High-Performing Older Adults
The results suggest that low- performing older adults recruited a similar network as young adults but used it inefficiently, whereas high-performing older adults counteracted age-related neural decline through a plastic reorganization of neurocognitive networks.
Spatial Pattern Analysis of Functional Brain Images Using Partial Least Squares
Partial least squares serves as an important extension by extracting new information from imaging data that is not accessible through other currently used univariate and multivariate image analysis tools.

Emerging concepts for the dynamical organization of resting-state activity in the brain
Three large-scale neural system models of primate neocortex that emphasize the key contributions of local dynamics, signal transmission delays and noise to the emerging RSNs are reviewed.
Age-Related Differences in Neural Activity during Memory Encoding and Retrieval: A Positron Emission Tomography Study
The results indicate that advanced age is associated with neural changes in the brain systems underlying encoding, recognition, and recall that take two forms: age- related decreases in local regional activity, which may signal less efficient processing by the old, and age-related increases in activity,Which may signal functional compensation.

Increased Brain Signal Variability Accompanies Lower Behavioral Variability in Development
Brain signal variability increased with age, and showed strong negative correlations with intrasubject RT variability and positive correlations with accuracy, suggesting that the moment-to-moment variability in brain activity may be a critical index of the cognitive capacity of the brain.
Blood Oxygen Level-Dependent Signal Variability Is More than Just Noise
This work examined fMRI signal variability during fixation baseline periods, and compared SD- and mean-based spatial patterns and their relations with chronological age, and found that not only was the SD-based pattern robust, it differed greatly, both spatially and statistically, from the mean- based pattern.
