In a morphometric study of the anterior cerebellar vermis of 47 brains
in the Yakovlev collection, the area of the vermis of 5 of 12 brains of
schizophrenic patients was smaller than that of any of 11 brains of control
subjects without psychiatric or neurologic disease and 9 of 10 brains of
control subjects with other psychiatric diagnoses (p less than .02). This
finding confirms computerized tomography scan observations in live patients
and supports the idea that some schizophrenic patients have structural
abnormalities of the cerebellar vermis.
