Neuroplasticity Flashcards
A weakly connected network leads to…
a) low plasticity
b) high plasticity
b) high plasticity
A weakly connected network leads to high plasticity, i.e. a high susceptibility to change the state of the system.
A strongly connected network leads to low plasticity, i.e. a low susceptibility to change the state of the system.
An unfavourable environment and high plasticity…
a) promotes wellbeing
b) increases vulnerability
b) increases vulnerability
High plasticity + unfavourable environment: increases vulnerability.
High plasticity + favourable environment: promotes wellbeing.
An unfavourable environment and low plasticity…
a) slows down improvement
b) prevents worsening
b) prevents worsening.
Low plasticity + unfavourable environment: prevents worsening.
Low plasticity + favourable environment: slows down improvement.
What are 3 types of neuroplasticity?
- Chemical change
- Structural change
- Functional change
How can neurogenesis be blocked?
Chemotherapy: blocks division of cells
Homeostatic synaptic plasticity requires presence of
a) Calcineurin
b) Protein phosphatase2C
a) Calcineurin.
Calcineurin mediates homeostatic synaptic plasticity by regulating the synthesis of retinoiuc acid (Vit. A), which disinhibits AMPA-R translation
Retinoiuc acid (Vit. A), whose synthesis is regulated by Calcineurin in mediating homeostatic synaptic plasticity, disinhibits AMPA-R translation…
a) systemically
b) locally
b) locally.
A neuron in the periphery can compensate for input imbalances through local mechanisms, eliminating the need to relay signals back to the nucleus (neuronal DNA).
What is the role of microglia in neuroplasticity?
a) surveillance of microenvironment facility of synapse
b) Inhibiting synaptic remodeling to maintain a fixed neural structure
a) surveillance of microenvironment facility of synapse
If synapses are not active anymore, microglias “eat” them, leaving dendroids “naked”
What is NOT a potential inductor of neuroplasticity?
a) ECT
b) MST
c) TMS
d) diet
e) exercise
f) beta-blockers
g) antidepressants
h) ketamine
f) beta-blockers
What is the purpose of iPSC-derived neurons on a chip?
a) Modeling human neural cells
b) Generating genetically modified neurons for gene therapy
a) Modeling human neural cells.
iPSC-derived neurons on a chip allow the generation of human neural cells from stem cells for studying neural function and disease.
