Neuroplasticity

Question 1

Use it or lose it

Answer 1

Neural circuits not actively engaged in task performance for an extended period of time begin to degrade

Left sided weakness, left arm movement is effortful, left arm movement attempts are unsuccessful, compensatory behavior by using the right arm for most tasks, learned not use of left arm

Question 2

Use it and improve it

Answer 2

Training that drives a specific brain function can lead to an enhancement of that function

Question 3

Specificity

Answer 3

The nature of the training experience dictates the nature of the plasticity

Question 4

Repetition matters

Answer 4

Induction of plasticity requires sufficient practice

Question 5

Intensity matters

Answer 5

Induction of plasticity requires challenging current capacity

Question 6

Time matters

Answer 6

Different forms of plasticity occur at different times during training

Question 7

Salience matters

Answer 7

The training experience must be sufficiently meaningful to induce plasticity

Question 8

Age matters

Answer 8

Training induced plasticity occurs more readily in younger brains

Question 9

Transference

Answer 9

Plasticity in response to one training experience can enhance the acquisition of similar behavior

Question 10

Interference

Answer 10

Plasticity in response to one experience can interfere with the acquisition of other behaviors
