Location: Lower regions of the cerebellum, extends from midline laterally
Description: Best to identify and label the boundary for VIIIB before VIIIA as the lower boundary can be difficult to identify otherwise
- The fissure between this lobule and Lobule VIIA Crus I is easily identified in the midsagittal slice as seen in Figure 63
This lobule usually consists of one or two white matter branches and its second boundary is characterized by the exclusion of VIIIB which has a distinct curve.

Figure 1 : Clear and easy example of VIIIA
Figure 2 : The boundary between VIIIA and VIIB was difficult in this scan and was finally determined using the preperventure fissure in the sagittal view.
Figure 3 : Sometimes 8A has two distinct branches.
Figure 4 : 8a wraps around 8b in an unusual way.
