Deck 25: Extension: B - Plasticity, Recovery, and Rehabilitation of the Adult Brain

Question 1

What evidence is there that sensory maps can be modified by experience?

Answer 1

Evidence for sensory map modification stems from studies of early blindness. Early blindness leads to expansion of auditory behavior into regions (parietal and occipital) that would otherwise not have that function.

Question 2

Use the following to answer questions:
Match the researchers in each question with the most appropriate focus.
Elbert et al. ___

A)musical scale in musicians
B)grasp techniques
C)human synapse
D)focal hand dystonia

Answer 2

focal hand dystonia

Question 3

What evidence is there that the response to adapting prisms causes actual synaptic changes in the brain?

Answer 3

Cellular change in neuronal firing in areas V1 and V4 ipsilaterally and contralaterally occur as a result of wearing the prisms. Moreover, these prisms have been used successfully in the treatment of visual neglect in stroke patients.

Question 4

What is the relationship between neuronal cell complexity and the computational demands on the cell?

Question 5

What is kindling in the brain?

Question 6

What is the relationship between high intelligence and recovery from brain injury? Why might highly intelligent people complain more about the negative residual effects of brain injury?

Question 7

Your patient is a well - educated woman of forty - five. She experienced a left - hemisphere stroke three weeks ago that has caused moderate aphasia. What is your counsel for your patient and her family?

Question 8

The authors list four major therapeutic approaches to brain damage. What are they?

Question 9

What is LTP?

Question 10

Use the following to answer questions:
Match the researchers in each question with the most appropriate focus.
Pantev et al. ___

A)musical scale in musicians
B)grasp techniques
C)human synapse
D)focal hand dystonia

Question 11

What evidence is there that motor maps can be modified by experience?

Question 12

What is the relationship between age at time of brain injury and recovery? What is disheartening about Teuber's analysis of this relationship?

Question 13

Why do the authors of the textbook call compensation the "problem of the three - legged cat"?

Question 14

Use the following to answer questions:
Match the researchers in each question with the most appropriate focus.
Nudo et al. ___

A)musical scale in musicians
B)grasp techniques
C)human synapse
D)focal hand dystonia

Question 15

What is the sequence of recovery (four stages) seen by Twitchell in brain - damaged patients?

Question 16

Use the following to answer questions:
Match the researchers in each question with the most appropriate focus.
Jacobs et al. ___

A)musical scale in musicians
B)grasp techniques
C)human synapse
D)focal hand dystonia

Question 17

Why did a brain - injured motorcycle racer show drastic improvement in both attitude and recovery after he was given a large tricycle on which to ride around?

Question 18

What is the relationship between the complexity of behavioral function and the complexity of dendritic arborization associated with that function? Give an example.
