Hi; I like using pubbrain and have found it to be instructive for showing the anatomy implicated in specific disorders, such as autism.  However, I can't seem to make the 'AND' function work in the query.  PubMed tells me that there are 2072 publications on the query for "autism AND schizophrenia", but PubBrain on the same query (http://www.pubbrain.org/brain/view/autis...) returns no results and the query gets into some sort of loop that has to be canceled from popup.

Any ideas?  Is AND not supported?

Thanks.
