Fig 4 Data: Longitudinal Brain Network Coupling and Cognitive Flexibility in Aging

Xing Qian published the underlying numerical data for Figure 4 on figshare in April 2026. The dataset likely contains longitudinal measurements of brain structure-function integration within the executive control, default mode, and salience networks, and their association with cognitive flexibility test scores. The data is derived from resting-state fMRI and diffusion MRI scans across two independent aging cohorts.

Use Cases

• Modeling the relationship between brain network coupling/decoupling and cognitive flexibility decline based on the described longitudinal associations.
• Analyzing aging-related changes in functional signal alignment within the salience and default mode networks based on the described network-specific trajectories.
• Investigating the spectral components of structure-function integration based on the graph signal processing framework mentioned in the description.
• Correlating Trail Making Test and Color Trails Test performance with neuroimaging-derived metrics based on the described measurement approach.

Strengths

• Data is derived from two independent longitudinal aging datasets, as stated 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 dataset is very small (14.0 KB), indicating limited scope, likely summary statistics or a small table.
