Pontocerebellar projection length

[katherine kollins]

I'm working on co-cultures of cerebellar cells with pontine explants,
and am wondering what the average distance is from mossy fiber projections
of the pontine nuclei to the IGL of the cerebellum in both mouse and rat 
(in vivo).  Any suggested mouse/rat brain atlas that would give me this 
information would be greatly appreciated, too.

Thanks for your assistance,
