Plasticity & Functional Recovery Flashcards
What is the meaning of plasticity?
. Brains tendency to change or adapt because of the experience of learning
What is maguire et als study about
. 16 male London taxi drivers and 50 non male taxi drivers
. Using MRI to show amount of grey matter
. Found that taxi drivers had larger hippocampus to control group, control group spending time with taxi driver also increased this
Advantages of this study?
. Highly empirical as it uses MRI
Limitations of this study
. Low population validity (
only 16)
. Evidence is based using correlations
Generally advantages of plasticity in the brain?
. Evidence to support that plasticity does not decline with age (Ladina)
General disadvantage of plasticity?
. Negative plasticity (phantom limb)
What is functional brain recovery?
Form of plasticity, following damage through trauma the brain can redistribute and transfer function from a undamaged area to a damaged area
What happens to the brain during functional recovery
. Axon spouting
. Enervation super sensitivity
. Recruitment of similar areas on opposite side of brain
What happens in danellis key study
.EB was operated on at the stage of 2 1/2 removing large tumor from left hemisphere
. All linguistic ability gone, but started rehabilitation
. At age 5 improvement found, when tested again at 17 found right hemisphere compensated and he was functioning well
Strengths of danelli
. Practical application of functional recovery
. Shows info about recovery and age
Limitation of danelli
. Educational attainment influenced how well the brain functions after injury
