abstract：:The phenotypic effect of the weaver mutation in the ventral midbrain of homozygous mutants is associated with the progressive loss of dopaminergic neurons. To discover whether the number of mesencephalic dopaminergic cells is altered in weaver heterozygotes (wv/+), we studied mice between 20 and 365 days of age. We co...
