Princeton RAtlas (PRA): Average Rat Brain Image Stack

Princeton RAtlas (PRA) is a 9.5 GB TIF image stack of sagittal slices providing an average brain atlas for Rattus norvegicus rats. It was created by Emily Dennis and described in a 2023 Bio-Protocol publication. The dataset includes separate male (mPRA) and female (fPRA) atlases defined by external genitalia.

Use Cases

• Spatial registration of experimental neuroimaging data based on the provided common coordinate framework.
• Comparative anatomical studies of rat brain structures using the average brain template.
• Development of automated image analysis pipelines for rat brain sections using the standardized atlas.

Strengths

• Dataset size is 9.5 GB, indicating a detailed image stack.
• Provides separate atlases for male and female rats based on a defined biological criterion.
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some quantitative analyses.
