Cerebellar folia: Leaf-like folds of the cerebellar cortex separated from each other by sulci and supported by a core of white matter.
Dentate nucleus: One of the deep cerebellar nuclei embedded in the deep white matter. Resembles the inferior olive in its purse-like appearance. Receives axons of Purkinje cells of the cerebellum as well as collaterals from the two major afferent bundles to the cerebellum; and projects through the brachium conjunctivurn to the red nucleus and ventrolateral nucleus of the thalamus. Lesions of the dentate nucleus result in homolateral volitional tremor.
Brachium conjunctivum: Outflow tract of the cerebellum. Heavily myelinated. Projects to the red nucleus and ventrolateral nucleus of the thalamus. Lesions of this tract result in homolateral volitional tremor.
Deep white matter: A compact mass of white matter, which is continuous between cerebellar hemispheres. In it are embedded the deep cerebellar nuclei. Extends into the folia as a core of white matter.
