functional recovery Flashcards
1
Q
what is functional recovery?
A
example of plasticity, following physical injury/ other form of trauma eg infection/stroke. unaffected areas able to adapt/compensate for areas damaged
2
Q
how does functional recovery occur?
A
- happens quickly after trauma (spontaneous recovery) + then slows down after weeks/months. rehab may be needed
- brain rewire + reorganise itself by forming new synaptic connections
- secondary neural pathways unmasked so new connections in brain activated and recover damage
3
Q
3
processes supported by structural changes
A
- axon sprouting
- neural regeneration
- recuritment of homologous area
4
Q
structrual changes
what is axon sprouting?
A
existing neurons growing new axons to connect to neurons
5
Q
structural changes
what is neural regeneration?
A
growth of new neuronal cells
6
Q
structural changes
what is recruitment of homologous area?
A
opposite hemisphere does specific task lost from damaged hemipshere eg Broca area damaged in left=right take over
