FUNCTIONAL UNITS OF THE CEREBELLUM - SAGITTAL ZONES AND MICROZONES

The functional units of the cerebellar cortex have been identified as sagittal zones with a width of about 1 mm and a length of up to more than 100 mm. These zones can be divided into sagittal microzones with a width of 200 μm or less. The microzones and their efferent relay neurones in the cerebellar nuclei might form the operational units of the cerebellum, corresponding in a sense with the classical cell columns of the cerebral cortex. © 1979.
