(1) Neuroplasticity Flashcards
to promote recovery instead of maladaptive compensations, PTs must be aware of what 2 things
- learning potential
- resources - environment, task, individual
what is neuroplasticity
how brain learns new behaviors AND how damaged brain learns new behaviors
does learning replace damaged neurons?
no, it reorganizes the damaged brain
brain damage changes the way the brain _______ to learning
responds
what is anormal response to damage
compensatory strategies
what principle says - neural circuits will degrage over time is not used in task performance
use it or lose it
what principle says - failing to engage the brain may decrease function further
use it or lose it
what principle says - extended training may drive enhancement of function, optimize brain plasticity
use it to improve it
what principle says - nature of training dictates nature of plasticity
- skill acquisition associated with enhancement of motor cortex
- training needs to match desired outcome
specificity
what principle says - if its boring to the brain, fewer synapses will be added
specificity
what principle says - repetitions of newly learned behavior leads to lasting neural changes
repetition
what principle says - need acquisition of skill with continued performance and reps strengthen behaviors making them less likely to decay
repetition
which principle supports a strong use of HEP
repetition
what principle says - it is possible to overuse
- overuse will lead to a decline in function
intensity
what principle says - different forms of plasticity occur at diff times in training
time matters
- time delay of neuroplasticity after brain damage leads to _____
compensaiont
what principle says - training must be important
- motivation and attention lead to task engagement
salience
how is neuroplasticity impacted by age
occurs more readily in young
- as we age, widespread neuronal and synaptic atrophy
can older brains learn?
yes, but may be less profound or slower progression
what principle says - plasticity in response to one training experience can enhance the acquisition of similar behaviors
transference
what principle says - plasticity in response to one experience can inhibit the acquisition of other behaviors
interference
