How do I find out if a hormone is distributed in a certain brain region? Actually it’s about endogenous ouabain. As for why I can’t find it, I don’t know whether I don’t know how to find it or it is not available in this database at present. ---

For all of our atlases, gene names can be typed into the search box. This will search the gene names, gene symbols, and any other names for a given gene that we have in our database. If you can’t find your hormone that means that either (1) it is not a mammalian gene or (2) the gene has changed names and we don’t have the new name in our system. A quick Google search suggests that ouabain is derived from plants and therefore would not be expected in a mammalian gene database. ---

I need epigenetic information. The centromedian thalamus and central amygdala should show so called ,sex dimorphic gene expression“. Where I can find them? ---

Would the Allen Institute provide me this kind of data if I would pay? Centromedian thalamus : which genes are expressed sex dimorphic Mediodorsal thalamus: dito Central Amygdala : dito Corticomedial amygdala:dito Mostly centromedian thalamus and central Amygdala, because these two brain structures are very high of AR receptors. ---

Please see [this post](https://community.brain-map.org/t/centromedian-thalamus-central-amygdala/1781) for the epigenetic information discussion. All data that is available is listed at [brain-map.org](http://brain-map.org), [biccn.org](http://biccn.org), or the associated data archives. There is no need to pay.
