Adult Lifespan Effects on Hippocampal Functional Specialization

337 humans aged 18–88 contributed resting-state fMRI data to investigate functional differentiation along the hippocampal long axis. Caitlin R. Bowman authored this research dataset, which was last updated in May 2026. The study measured correlations within hippocampal subregions and their functional connectivity with the rest of the brain.

Use Cases

• Analyze age-related changes in hippocampal signal similarity based on within-subregion correlation data.
• Model functional connectivity trajectories between hippocampal subregions and frontal brain regions across adulthood.
• Investigate the relationship between hippocampal functional organization and episodic memory performance.
• Compare posterior versus anterior hippocampal signaling heterogeneity across the adult lifespan.

Strengths

• Includes 337 human subjects, providing a substantial sample size.
• Covers a wide adult lifespan age range from 18 to 88 years.
• Uses two methodological approaches: within-hippocampal correlation and whole-brain functional connectivity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is stored as a 1.2 MB DOCX file, which suggests the primary data may be embedded within a document rather than a standalone structured table.
