Motor Learning & the cerebellum

Question 1

What is hierarchical organization of motor system?

Answer 1

Progressively higher levels in the system select and modify patterns generated by the lower levels

Question 2

What is the UCS of eye blink conditoining?

Answer 2

puff of air to the cornea

Question 3

what is the UCR of eye blink conditioning?

Answer 3

Blink

Question 4

What is the CS of the eye blink conditioning?

Answer 4

Tone

Question 5

What is the CR of the eye blink conditioning?

Answer 5

The timing of the blink to be at maximum blink when the puff of air happens not after

Question 6

What organism was the eye blink study performed?

Answer 6

Rabbits cause they sit still

Question 7

What are the two possible places in the eyeblink conditioning pathway are possible sites for plasticity?

Answer 7

Cerebellar cortex and the Interpositus nuclei

Question 8

Why are these two places possible of plasticity?

Answer 8

They have two or more inputs into the area, LTP/LTD

Question 9

What is the basic evidence for interpositus nuclei as a site of plasticity?

Answer 9

Stimulation of anterior interpositus produces a blink

Question 10

What is better evidence for the interpositus nuclei as the site of plasticity?

Answer 10

There is an increase in activity in the interpositus nuclei before the eye blink happens

Question 11

What is the “noise” in this study of the interpositus nuclei as the site of plasticity?

Answer 11

The cerebellar cortex cannot activate the red nucleus
