Systematic fMRI signal differences across cohorts alter lifespan trajectories of functional brain networks

The paper examines how systematic fMRI signal differences across cohorts affect lifespan trajectories of functional brain networks and shows how harmonization can mitigate these effects.

Lower Levels of Task-Induced Hippocampal Activation Predict Better Performance on a Separate Verbal Memory Evaluation

The paper replicates and extends a negative correlation between hippocampal activation during a verbal memory task and subsequent verbal memory test performance.

Parallel Hippocampal-Parietal Circuits for Self- and Goal-oriented Processing

The paper identifies distinct functional connectivity patterns in the hippocampus, showing anterior regions connect to the default mode network and posterior regions connect to the parietal memory network, supporting different cognitive processes.

Removal of high frequency contamination from motion estimates in single-band fMRI saves data without biasing functional connectivity

This paper identifies and removes high-frequency motion artifacts in single-band fMRI data, improving motion estimates and reducing data loss without biasing functional connectivity.
