Neuroplasticity UPDATED ACTUAL Exam
Questions and CORRECT Answers
Which concepts are promoted by the idea of neuroplasticity?
a. external locus of control and fixed mindset
b. internal locus of control and fixed mindset
c. external locus of control and growth mindset
d. internal locus of control and growth mindset - CORRECT ANSWER d
What are the two kind of neuroplasticity? Define each. - CORRECT ANSWER 1.
Structural neuroplasticity: brain's ability to change its neuronal connections. Includes changes in
size of brain regions and grey matter proportions, assessed with neurimaging
2. Functional neuroplasticity: the brain's ability to alter and adapt the functional properties of
neurons. Includes strengthening / weakening of synapses through LTP
What is LTP (long term potentiation)? - CORRECT ANSWER Long term increase in
excitability of a neuron to a particular synaptic input caused by repeated high-frequency activity
of that input
When London taxi drivers are required to memorize thousands of streets, how do their brains
change? - CORRECT ANSWER Growth in posterior hippocampus
When medical students study for their final exams, how do their brains change? - CORRECT
ANSWER Increased grey matter in parietal and hippocampal regions
How does the grey matter density in the inferior parietal cortex differ between multilinguals and
monolinguals? - CORRECT ANSWER Multilinguals have greater density, and early
bilinguals have greater density than late learners
