1. Cerebellar flocculus
The flocculus is labelled here as the ‘cerebellar flocculus’ which is useful because it informs us the flocculus belongs to the cerebellum. Moreover, the flocculus works together with another cerebellar component, the nodulus, as part of the flocculonodular lobe: this lobe has important input to the vestibular system (as part of the vestibulocerebellum) and also influences eye movement.

In this view we see:
- An anterior view of the brainstem, partially obscuring the much broader posteriorly located cerebellum.
- All three divisions of the brainstem, from superior to inferior: the midbrain, pons and medulla. The midbrain, pons and medulla share a number of features including longitudinal fibre tracts, a tegmentum, and clusters of neurons called nuclei. While some longitudinal fibre tracts begin and terminate in the brainstem, others pass through it on their way between the cerebrum above and spinal cord below. These longitudinal tracts are present at all levels of the midbrain, pons and medulla.
