Brainspan Atlas is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The BrainSpan Atlas is a comprehensive developmental transcriptome resource that maps gene expression across the human brain from prenatal stages through adulthood. It is a collaboration between the Allen Institute and multiple academic institutions[1].
BrainSpan provides the most detailed available map of how gene expression changes during human brain development. This resource is invaluable for understanding normal brain development and neurodevelopmental disorders[1]. The atlas covers the entire span of human brain development, from embryonic stages through adulthood, making it unique among brain transcriptomic resources[2].
BrainSpan covers brain development from embryonic stages (8 weeks post-conception) through adulthood (40+ years). This comprehensive temporal coverage allows researchers to:
The atlas includes samples from multiple brain regions, developmental stages, both sexes, and diverse ethnic backgrounds. Samples are categorized by:
BrainSpan uses both microarray and RNA-seq technologies to ensure comprehensive coverage of the transcriptome. This dual-platform approach allows for:
| Data Type | Description |
|---|---|
| Transcriptomic | Gene expression levels across development |
| Splicing | Alternative splicing patterns |
| Annotation | Detailed anatomical metadata |
Understanding when and where specific genes are expressed during brain development helps identify critical periods for different brain functions. Researchers use BrainSpan to study:
Comparing expression patterns in developing brains with those affected by neurodevelopmental disorders can reveal disease mechanisms. BrainSpan data has been used to:
Comparing human brain development with other species illuminates what makes the human brain unique. BrainSpan integrates with other Allen Brain Atlas resources for cross-species comparisons[5].
