plasticity and functional recovery

Question 1

what is plasticity

Answer 1

the brains ability to change throughout life and the growth of new synaptic connections

Question 2

what is synaptic pruning

Answer 2

rarely used connections are delted and frequently used ones are strenghtend

Question 3

strength of plasticity

Answer 3

bezzola et al 2012
may be a life long ability
40-60 yr olds play golf have a increased motor cortex ability

Question 4

limitation of plasticity

Answer 4

negative behavioural consequences
phantom linb affects 60-80% of amputees
symptoms ar painful
effects somatosensory cortex

Question 5

whta is functional recovery

Answer 5

healthy brain areas take over functions of dAMAGED AREAS after trauma

Question 6

what are the three changes in the brain during functional recovery

Answer 6

axonal sprouting
denervation supersensitivity
recruitment of homogollous areas

Question 7

what is axonal sprouting

Answer 7

growth of new nerve endingd which connect with other undamaged nerve cells to form neuronal pathways

Question 8

what is denervation supersensitivity

Answer 8

axons that do a similar job become more aroused and compensate for lost ones
can cause pain

Question 9

whats recruitment of homogolous areas

Answer 9

specific tasks can still be performed and its just took over by the other side of the brain

Question 10

strencth of functional recovery

Answer 10

real world application eg neurorehabilitation
stroke patiens use the affected part of the body

Question 11

limitation of functional recovery

Answer 11

cognitive reserve
schnieder et al 2014
people with 16 yrs or more of education 40 %had a fulll recovery
less than 16yrs 10%
