This study demonstrates that the human cerebellum expresses the Purkinje cell antigen zebrin II. Two populations of Purkinje cells can be identified with high (P+) and low (P-) expression levels. MR imaging of the anterior cerebellum reveals a similar stripe array to that seen with anti-zebrin II immunocytochemistry. Although the underlying cellular mechanism for the image contrast remains to be determined, there is a positive correlation between the molecular target and the MR images. This unique application of MR may be very useful for studying cerebellar abnormalities during development and the progression of cerebellum-related neurological diseases.
