Functial Recovery^

Question 1

Functual Recovery

Answer 1

type of neural plasticity
unaffected brain regions can take over for the regions affected by trauma

Question 2

Spontaneus Recovery

Answer 2

functual recovery occurs quickly after trauma and slow down over time
may need rehab

Question 3

The Brain During Recovery

Answer 3

develops new synaptic connections around damaged area
the unmasking of secondary neural pathway
- not usually used for functions
- takes place to keep functioning properly

Question 4

Axonal Sprouting

Answer 4

Unused neurons being unmasked/ used to create new neural pathways/synaptic connections

Question 5

Denervation Supersensitivity

Answer 5

Undamaged axons with similar roles are highly stimulated
- to compensate for the damaged ones
Neg side effect
- oversensitivity to certain stimuli
= pain

Question 6

Recruitment of Homologous Areas on the Opposite Side of the Brain

Answer 6

Same region on the opposite hemisphere takes over the role of the damaged region until it has recovered

Question 7

Real World Application

Answer 7

Findings from axonal growth has lead to therapies being developed
- constraint induced movement therapy for those who had a stroke

Question 8

Cognitive Reserve

Answer 8

how educated an individual is can affect their rate of recovery

• Schneider et al
  : more educated = higher rate of disability free recovery
  : 40% of DFR had over 16 years edu.
  : 20% had less that 12 years

Question 9

VS Cognitive Reserve

Answer 9

not representative
DFR can’t be applied to all as not all have access to education
Can be due to factors outside control such as financial issues

Question 10

Stem Application

Answer 10

Benerjee et al
- treated P who had a stroke with stem cells
- every patients in trail recovered VS 4% that usually recovers without stem

Question 11

VS Stem Application

Answer 11

Small sample
it had only 5 patients
no control group
- not generalisable as it needs a bigger sample
