Rat Hippocampus 3D EM Images and Synapse Reconstructions for LTP/LTD Study

Four-component 3DEM dataset from the rat dentate gyrus, supporting a 2025 paper on astroglial responses to synaptic plasticity. Serial-section EM images are paired with PyReconstruct trace files, 3D Blender reconstructions of tripartite synapses, and a CSV of quantitative measurements. The dataset is hosted on the 3dem.org public data cloud.

Use Cases

• Train segmentation models for synaptic components based on serial-section EM images.
• Analyze 3D morphology of tripartite synapses using the provided .blend reconstruction files.
• Conduct statistical analysis of synaptic measurements using the summary .csv file.
• Validate computational tracing algorithms against the provided PyReconstruct .jser trace files.

Strengths

• Dataset includes four distinct, complementary file types (images, traces, 3D models, summary data).
• Data is directly linked to a specific, recent 2025 research publication.
• Publicly available for download from a dedicated neuroimaging data repository (3dem.org).

Limitations

• Column-level documentation for the summary .csv file is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
