What is the function of gray matter in the brain? (436)

• To produce neurotransmitters

• • To conduct electrical impulses

• To store memories

• To contain neuron cell bodies

What is the function of the cerebellum? (454)

• To process visual information

• • To regulate heart rate

What suggests that the cerebellum may play a role in thinking, language, and emotion? (454)

• Neuroanatomy, imaging studies, and observations of patients with cerebellar injuries

• Motor coordination

• • Sensory processing

• • Auditory perception

What do the middle cerebellar peduncles carry? (454)

• Instructions from the cerebral motor cortex to the cerebellum

• Sensory information to the cerebellum

• One-way communications from the pons to the cerebellum

• Sensory information from muscle proprioceptors to the cerebellum

What is the function of the superior cerebellar peduncles? (454)

• • To carry instructions from deep cerebellar nuclei to the cerebral motor cortex

• • To carry sensory information from muscle proprioceptors

• • To carry voluntary motor activities from the pons to the cerebellum

• To carry equilibrium information to the cerebellum

Which lobes of the cerebellum coordinate body movements? (454)

• Anterior lobe

• Posterior lobe

• All lobes

• Hemisphere lobes

What type of neurons send axons through the white matter to synapse with the central nuclei of the cerebellum? (454)

• • Purkinje cells

• Motor neurons

• Sensory neurons
