1
Q
when is the brain most plastic
A
during early dev
2
Q
what are changes to the brain that occur during early dev?
A
GROWTH of dendrites and axons
synaptogenesis
myelination
pruning (of neurons/connections that arent’ used)
3
Q
effect of learning on plastiicty
A
dendritic branching
potentiation: results in excitatory repsonse being stronger and more prolonged (long term = LTP).
4
Q
effect of plasticity on CNS nerve injury
A
sadly very limited
5
Q
describe adult neurogenesis
A
occurs in hippocampus and cerebral cortex
6
Q
implications of adult neurogenesis?
A
could help recover from brain injury
7
Q
how could stem cells be used
A
implanted
genes chnaged so they can admintser gene therapy
