Longitudinal Brain Structure-Function Integration Data for Cognitive Aging Study

Xing Qian's research data from a study on cognitive aging, published on figshare in 2026. The underlying numerical data supports analysis of how brain network integration changes with age and relates to cognitive flexibility. The dataset is 12.9 KB in size and is available in XLSX format.

Use Cases

• Modeling the relationship between brain network coupling/decoupling and cognitive flexibility scores based on the Trail Making Test and Color Trails Test.
• Analyzing longitudinal changes in functional signal alignment within the executive control, default mode, and salience networks.
• Investigating network-specific aging trajectories, such as decreased coupling in the salience network versus increased coupling in the default mode network.

Strengths

• Data is derived from two independent longitudinal datasets, as mentioned in the description.
• Focuses on three core large-scale cognitive systems: the executive control, default mode, and salience networks.
• Published under a CC-BY-4.0 license, permitting open sharing and reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 12.9 KB file size indicates a very small, likely summary-level dataset.
