Dentate Nucleus

Nucleus dentatus

The largest deep cerebellar nucleus: carries the output of the lateral hemispheres via the thalamus to motor and prefrontal cortex.

Anatomy

  • In the hemispheric white matter, shaped like a crumpled bag; its hilum faces medially and forward.
  • Output: superior cerebellar peduncle → contralateral red nucleus and thalamus (VL) → cortex.

Functions

  • Motor planning and timing (dorsal part).
  • Cognitive functions: its ventral part forms a loop with the prefrontal cortex (Dum and Strick, 2003).

Clinical

  • Dentate nucleus atrophy in Friedreich ataxia.
  • Disorders of the dentato-thalamo-cortical pathway cause tremor and ataxia.
