Molecular layer heterotopia of the cerebellar vermis in mutant and transgenic mouse models on a C57BL/6 background

Highlights • Mutant mice on a C57BL/6 background exhibit cerebellar heterotopia. • Cre-transgenic mice on a C57BL/6 background exhibit cerebellar heterotopia. • Cerebellar heterotopia may affect results from studies with mutant/transgenic mice.
