Lobule IV

  • Location: Top portion of the cerebellum, focused around the midline
  • Description: It can first be identified in the midsagittal slice, as the lobule to the left (inwards) of the top most vertical fissure.
  • It is bounded on one side by lobule III. On the other the boundary is the most prominent fissure between llobule III and the primary fissure.
