Week 6 Neuroplasticity Flashcards
What is neuroplasticity?
Is the brain ability to change for better or worse.
What is the process of neuroplasticity involves what?
Forming neuronal connection in response to sensory stimuli from the environment and normal development.
What is the positive outcome of neuroplasticity?
Able to develop new skills
Better cognition
Efficient communication between sensory motor function.
What are the negative outcomes of neuroplasticity?
Decline in brain function
Altered motor control
Amplified pain.
True or False. The brain is pliable, plastic, and changeable throughout our lives?
True
When is the brain at most plastic?
During child age. When the brain is developing.
What is a Cortical Maps?
Changes in the cortex occur in association with adaptive responses to the environment through everyday activities.
What would be the example of Cortical maps?
Mirror image for phantom pain limb. Decreased pain.
What is Neurogenesis?
The production of new neurons in the brain.
What helps neurogenesis to grow?
Physical activity
What is Synaptogenesis?
Formation of synapses between neurons.
What is Hebb’s Rule?
Changes and synaptic change account for learning. This happens during activities that we want to complete. Strengthening of neurons with other neurons.
When does the Hebb’s Rule occur?
When a person performs a task repeatedly to learn or relearn a skill
From where does this quote come from? Neurons that fire together, wire together?
Hebb’s Rule
What are the 7 Tenets of Neuroplasticity?
- Change can only occur when the brain is in the mood.
- Change strengthens connections between neurons at the same time.
- Neurons that fire together wire together
- Initial changes are just temporary
- Brain plasticity is a two way street (positive and Negative)
- Memory is crucial to learning
- Motivation is key
What are the tips for optimal Plasticity?
- Heart needs to be in shape. The heart supplies the brain with oxygen so circulation is important
- Training should be incremental. Just the right challenge. Increase difficulty systematically.
- Taxing, systematically improving. The difficulty, just the right challenge and need to be successful
- Should be intresting to engage the motivation circuits in your brain. Motivation is the key
What is Procedural Learning?
Occurs for tasks that are particularly autonomic (without attention or consciousness)
Learn through repeated practice in varying contexts
Verbal instructions little help, need hands-on practice, practice
Learning is expressed through performance
What is Declerative Learning
Created knwoledge that can be recalled.
Learning can be verbalized by naming the steps of the task.
Mental rehearsing is commonly used (review the activity mentally or by verbalizing the steps/process)
With repetition declarative learning can become procedural.
Who is more appropriate for Procedural learning?
Clients with limiting cognition
Who is more appropriate for Declarative Leaning?
Not for cognitive or language disorders requires mental activity.
Approrpate for patients who have low activity tolerance, fatigue can do as much repetation that is required.
