In using gene expression databases, a "search by example" feature is also highly desirable as genes with similar expression patterns may be related in function. The "Find Correlates" search utility will accomplish this function. This search by example facility is also available in the Allen Mouse Brain Atlas and Allen Developing Mouse Brain Atlas and the NIMH Transcriptional Atlas of Human Brain Development.
To find other genes with profiles similar to your gene of interest, first select your probe by clicking on any cell in the heat map related to that probe. You will see that probe listed in the box above the right hand side of the heat map. Then select the brain structure(s) in which you would like to see a similar expression pattern, and click "Find Correlates". This action will return probes with a similar expression profile to brain region(s) in which you are interested. Only regions selected for the search will be displayed. To see the search results across the entire brain, turn off the "Restrict Domains" function at the bottom of the heat map.
You can see "anti-correlated" returns by toggling the sort order on column "r" or scrolling to the bottom of the heatmap.
