HUS2-41 Cerebellum

The structure well-known for sending error signals to cerebellum is

• inferior olivary nucleus

• red nucleus

• pontine nucleus

• dentate nucleus

Cerebellar inputs come from ipsilateral side, except for what fibres?

• trigeminocerebellar

• olivocerebellar

• pontocerebellar

What is the neurotransmitter released by climbing fibres and mossy fibres? Is it excitatory or inhibitory?

• Glutamate +

• Glutamate -

• Aspartate +

• Aspartate -

• GABA -

Climbing fibres receives input mainly from

• superior cerebellar peduncle

• inferior cerebellar peduncle

• superior olivary nucleus

• inferior olivary nucleus

• Purkinje cells

VSCT enters cerebellum via

• superior cerebellar peduncle and the peduncle does not decussate

• superior cerebellar peduncle and the peduncle decussates

• middle cerebellar peduncle and the peduncle does not decussate

• inferior cerebellar peduncle and the peduncle does not decussate

• inferior cerebellar peduncle and the peduncle decussates

Pontine nuclei relay input from where to the cerebellum?

• spinal cord

• red nucleus

• cerebrum

• inferior olivary nucleus

• ventral lateral thalamus

Which part of the cerebellum is responsible for performing skilled movement?

• FN lobe

• Vermis

• Lateral zone
