Figure: Screenshot of top returns of a differential search for genes with higher expression in the thalamus than the cerebral cortex. Z-score heatmap shows enrichment (red) in the thalamus (structure color: light green) compare to other brain regions.

Usage of this service is demonstrated in the SPM example application.
