Plasticity

Question 1

Explain the concepts of functional recovery

Answer 1

function- able to return to previous capability
recovery vs compensation
sparing if function
stages of recovery

Question 2

Define neuroplasticity

Answer 2

the ability to show a modification in response to activity and behavior»adapting, learning, and recovering from injuries VIA new synaptic connections

Question 3

the process of long-term potentiation

Answer 3

1) presynaptic release of NTs
2) Repeated stimulus>increased NT release
3) Over time, the same stimulus level= strength increase
4) long term potentiation> learning

Question 4

Why do we see the brain reorganize instead of recovery after injury?

Answer 4

we don’t repair the cell bodies lost, we just find ways to rewire what is already there as we adjust to new things or compensate for impairment

Question 5

What are the two conditions in which plasticity occurs?

Answer 5

normal. development

response to injury or disease

Question 6

describe synaptogenesis

Answer 6

relating to development, birth is a time of rapid brain growth (1 neuron>2500 synapses and later 15000) but about 50% are pruned.

Question 7

How and why does the brain undergo synaptic pruning?

Answer 7

apoptosis is programmed brain death bc there aren’t enough chemical provisions (NTs?) by the targets. All ineffective connections are pruned.

Question 8

What helps our brain determine what neural connections should be strengthened,
pruned, and/or preserved.

Answer 8

EXPERIENCE! with most active connections being preserved

Question 9

List a few ways that a PT might implement plasticity

Answer 9

different approaches, learning styles and feedback,

cultural competency +ICF model to consider factors related to pt condition
