Cerebellar corticovestibular projections from lobule IX to the descending vestibular nucleus in the cat. A retrograde wheat germ agglutinin-horseradish peroxidase study.
The distribution of Purkinje cells projecting to the descending vestibular nucleus was studied in lobule IX (uvula) of the cat by the retrograde wheat germ agglutinin-horseradish peroxidase method. In the transverse plane labeled Purkinje cells were seen diffusely within 1.0 mm from the midline and densely for 250-500 microns at around 1.0 mm lateral to the midline. Reconstruction of the distribution in the horizontal plane revealed that they were distributed in longitudinal areas extending in the apicobasal extent of lobule IX.
