1

what are the deep nuclei in the vermis?

fastigial n. 

vestibular n.

2

motor function of the vermis and fastigial?

balance, eye movement, reflexes

3

cogntiive function of the fastigial and vestibular n. ?

autonomic arousal, limbic regulation

4

Nulcei in the paravermal hemisphere?

globose and emboliform

5

moor function of the globose and emboliform (intemediate paravermal hemisphere)?

sensorimotor integration, movement execution

6

sensory function of the  globose and emboliform  hemisphere (intemediate paravermal hemisphere)?

simple verbal

responses to commands

7

nuclei in the lateral hemisphere?

dentate

8

motot function of the dentate gyrus?

prepration and planning of movement

fine motor dexterity

eye movements

imagined movements

9

cognitive  function of thedentate gyrus

verbal associaiton

rule based learning

working memory

problem solving

monitoring performance

temporal perception

10

main inputs into the cerebellum? (3)

1. cerebrocerebellum: frontal and parietal

2. vestibular nuclei

3. spinocerebellar

11

where does the frontal/parietal lobes contribute to?

mostly the lateral hemispheres (think planning movements)

12

where does the spinal cord input to in the cerebellum?

vermis/some hemisphere

13

where do the vestibular nuclei input to in the cerebellum?

into the nodulus/flocculus

14

What is the cerebellum (in terms of cellular components)

The cerebellum = cerebellar cortex + deep nuclei + white matter tracts

15

How many layers does the cerebellar cortex have? what are they?

3 layers: Molecular, Purkinje cell, and Granule cell

16

The cell bodies of most mossy fibers entering the cerebellum are located in the ____

pons

17

The expansion of the lateral cerebellar hemisphere in humans indicates that  the cerebellum is capable of ___

contributing to more than just motor function

18

___ shows prominent activation during
extremely difficult problem solving tasks in humans? 

Dentate nucleus

19

The appearance of oscillating movements of the hand while reaching toward a target is
referred to as ___

intention tremor

20

The use of ethanol to control symptoms of essential tremor is effective because  ethanol (2)

 1. inhibits normal excitation

2. facilitates GABAergic function

21

which cerebellar n. is involved in 

autonomic arousal, limbic regulation

fastigal and vestibular

22

which cerebellar n. is involved in

simple verbal respponses to commands

globose and emboliform

23

which cerebellar n. is involved in

rule based learning, problem solving, temporal perception etc

dentate

24

which cerebellar n. is involved in

preparation and planning of movements

dentate

25

which cerebellar n. is involved in

sensoriomotr integration, movement ececution

globlose and emboliform

26

where are radial (bergmann) glial cells found

in the purkinje and moelcular layers of the cerebellar cortex

27

where are bushy astroglia found

in the granule layer

28

where are olgiodendrocytes found

in the white matter

29

where do purkinje cells project to

the deep cerebellar nuclei

30

____ - wrap around one Purkinje cell

Climbing fibers
