Re: [Fwd: Re: cell types, brain regions mentioned in gensat]

Thanks, Alan.

I'd posted a question about this statement on that Wiki page.  It  
didn't quite make sense to me but wanted to hear what it was  
originally intended to assert.

This is partly why I think its a good idea to look at the simpler,  
less expressive representation I have on the followup page.  I think  
it will be easier for us to apply to the current data sets we have in  
hand and to scale up.
