Plasticity
The brain's ability to rewire at a behavioral and cellular level.
What is neuroplasticity?
A ____ threshold means the post-synaptic neuron is ___ likely to fire an action potential.
lower; more
Plasticity occurs more rapidly at this time of your life.
What is childhood?
(critical periods)
This principle states, "neurons that fire together wire together."
Caused by practice, training, and new learning.
What is behavioral plasticity?
True of false: cellular neuroplasticity changes the PRE and POST synaptic neurons.
True
Neuroplasticity resulting from practicing a new skill.
What is behavioral/Experiential neuroplasticity.
This principle explains why you may lose a skill if you stop practicing.
What is "use it or lose it"?
Occurs when there are changes to neuronal firing and connections between neurons.
What is cellular or neural plasticity?
A physical change in the post-synaptic neuron when LTP is acheived.
What is an increase in AMPA receptors?
Two processes occurring during developmental neuroplasticity.
What is proliferation and/or pruning of synapses?
This type of practice is best for learning a new skills.
What is distributed practice?
Name one principle of neuroplasticity.
•Use it or lose it
•Use it and improve it (neurons that fire together wire together)
•Specificity – train the behavior we want (generalization)
•Repetition matters (errorless learning/practice = adaptative neuroplasticity)
•Intensity matters
•Time matters – when to intervene?
•Salience matters
•Age matters
•Transference matters – learning one behavior can help learn another
•Interference – plasticity in response to one experience can make acquisition of another skill more challenging
This occurs when there is an increase in AMPA receptors.
What is LTP?
True or false: In the brain of a person who is born blind, some portion of their occipital lobe may be allocated to tactile sensation.
True
This principle suggests that we train the behavior we want.
What is specificity?
The result of strengthening synapses and networks of synapses.
LTP
This occurs when a neuronal pathway is no longer used.
Neuroplasticity resulting from the brain healing after damage.
What is spontaneous recovery?
When learning one behavior helps to learn another.
What is the principle of transference?
