neuroblast vs. neuronal progenitor

[Doug howe]

Would everyone agree if I were to suggest that all GO terms that have 
"neuroblast" in the term name also have an exact synonym using the term 
"neuronal progenitor"?

Eg.
"neuroblast differentiation" would get an exact synonym of "neuronal 
progenitor differentiation".

Likewise, I would like to suggest a new term on SourceForge for 
"glioblast differentiation" with the exactly synonym "glial progenitor 
differentiation".

I realize that sometimes a single cells can pass through a stage during 
which it is a progenitor capable of generating neurons and glia in some 
cases..but I think this is OK..maybe we could even have a term like 
"neuro-glial progenitor differentiation" to represent differentiation of 
this type of cell?

What do you think?
