Purkinje cells in the cerebellum receive inhibitory noradrenergic input from the locus coeruleus. In pcd mutant mice all Purkinje cells degenerate by 45 days of age. The purpose of the present studies was to determine if the loss of these cerebellar neurons affects the amounts of norepinephrine in the cerebellum of mice 25-280 days of age. No significant changes in norepinephrine content were detected during or after Purkinje cell degeneration. However, since degeneration led to a reduction in cerebellar weight, the norepinephrine concentration was increased in pcd mutants. These results indicate that despite the loss of a major postsynaptic target (Purkinje cells), the cerebellar noradrenergic input remains stable.
