GTEx dataset
RNA-seq tissue data generated by the Genotype-Tissue Expression (GTEx) project is reported as mean pTPM (protein-coding transcripts per million), corresponding to mean values of the different individual samples for respective subregion. Highest expression among the subregions represents the brain region. To access sample data, click on region name or bar.

The GTEx RNA-seq assay is described in detail in Assays & Annotation.

HPA Prefrontal cortex dataset
This dataset is a stand-alone dataset not integrated with other human transcriptomics data presented in the brain atlas. Brain expression data obtained through RNA-seq generated by the HPA, reported as normalized expression (NX) for human prefrontal cortex samples. Color coding of the bars separates prefrontal cortex and the three reference cortex regions (frontal, parietal and temporal). Trimmed mean values are calculated for the different subregions, to access individual sample data, click on subregion name or bar.
