Employing tyrosine hydroxylase (TH) immunohistochemistry, we have revealed that TH immunoreactivity occurs in cerebellar Purkinje cells in the rat. These TH-immunoreactive Purkinje cells were distributed predominantly in the crus I & II ansiform lobules and the paraflocculus, and to a lesser extent in the I & X vermal lobules. Since Purkinje cells in such cerebellar regions displayed no immunoreactivity to dopamine-beta-hydroxylase, the TH-immunoreactive Purkinje cells identified in the present study might contain dopamine or L-DOPA.
