Neuroplasticity Flashcards
What is plasticity in the brain?
The brain’s ability to create adaptive changes to respond to
intrinsic or extrinsic stimuli by reorganizing its neuronal structure and function
Explain cortical reorganisation
Neurons mainly respond to a few key signals out of all the possible ones they receive. The brain can adjust the strength of these connections so that signals which were once weak can become stronger. This process is gradual, with important signals getting stronger through repetition, while unimportant ones become weaker. Small learning steps lead to big changes over time.
When is Acetylcholine released?

When is dopamine released?
When successful target achievement
Name the five keys to motor learning
- Focused attention and attempt
- Training specificity and variability
- Repetition of movement
- Muscle activation & feedback
- Engagement and success
How does FES and neuroplasticity work together?
Patient attempts to voluntarily execute a
motor task → motor command is
generated and sent
FES assists in executing the task
(synchronized activation of muscles)
Proper muscle activation → relevant
spatiotemporal afferent feedback
What kind of training is vital for increased cortical excitability?
motor skill training
Explain the Self-regeneration capacity of the CNS
FES therapy has the potential to functionally reconstruct the damaged neural circuits by
promoting the self-regeneration capacity of the CNS: regeneration of neural cells, repair of axons, synaptic connections according to the somatotopic maps and designated functions
