The section is laid so that it includes both the cerebellar cortex, white matter and one of the cerebellar nuclei, the nucleus dentatus.

Have a diagram of the major synaptic connections in the cerebellum available as you look at the section (from mossy and climbing fibers that bring information into the cortex to the neurons of the cerebellar nuclei that send responses out of the cerebellum).
