Microarray use case

[Kei Cheung]

I'm posting the following question to the neurolex group in the hope of 
getting some neuroscience domain expert input to our microarray use case 
(http://esw.w3.org/topic/HCLSIG_BioRDF_Subgroup/QueryFederation2 ).

One of the microarray experiments mentions "substantia nigra dopamine 
neuron". I searched neurolex and found the following: "substantia nigra 
pars compacta dopaminergic cell". Are they the same? As I understand it, 
pars compacta is a portion of substantia nigra

Thanks,
