HUF2-103 Locomotion and functions of the cerebellum

Which of the following is correct about CPG?

• It is believed to be located in the cerebellum.

• It does not require a descending nor sensory trigger.

• Pontine reticular formation can stimulate change in speed of CPG activities.

• Visually guided locomotion is always achieved even without the parietal cortex.

• CPG itself is sufficient for maintaining locomotor patterns for humans

• premotor cortex

• primary motor cortex

• posterior parietal cortex

• somatosensory association cortex
