Initial differentiation of neurons in the cerebellar anlage. a–c Expression of neuronal markers in the GAP-43 (+/+) E15.5 midsagittal cerebellar anlage. a Calbindin labels differentiating PCs migrating toward cerebellar cortex. b BEN also labels differentiating neurons in the same region. c GAP-43 immunoreactivity does not overlap with either calbindin or BEN but is concentrated in the fibrous zone and in the neuropil at region where the CeL will develop (asterisk). Scale bar=300 µm. In all cases, arrow indicates the region from which the insert (4×) was taken
