Plasticity and Functional Recovery Flashcards
A2 content
What is plasticity?
Ability of the brain to change and adapt its structures and processes as a result of experience and new learning
What is functional recovery?
the way that certain abilities of the brain may be moved or redistributed rather than lost following brain damage or trauma.
What period of time do we have a rapid growth of synaptic connections?
Infancy
What do we call it when the brain severs connections that are not used after the explosion of learning in infancy?
Synaptic pruning.
The growth of new nerve endings which connect with other undamaged nerve cells to form new neuronal pathways.
Axonal Sprouting.
What is the purpose of blood vessel reformation?
Facilitates the growth of new neural pathways
This occurs when axons that do a similar job become aroused to a higher level to compensate for the ones that are lost. However, it can have the negative consequence of oversensitivity to messages such as pain.
Denervation supersensitivity
Give an example of recruitment of homologous areas?’
An example would be if Broca’s area was damaged on the left side of the brain, the right-sided equivalent would carry out its functions. After a period of time, functionality may then shift back to the left side
What was the findings of Maguires (2000) Taxi Driver study?
Found significantly more volume of grey matter in the posterior hippocampus than in a matched control group.
