SYNAPTIC PLASTICITY

Question 1

Synaptic plasticity

Answer 1

-the ability of synaptic connections to
change over time in response to activity or experience

Question 2

three mechanisms of synaptic
plasticity

Answer 2

-sprouting
-rerouting
-pruning.

Question 3

Sprouting

Answer 3

the ability of dendrites or axons to
develop new extensions
or branches

Question 4

Rerouting

Answer 4

the ability of a neuron that is connected
to a damaged neuron to create an alternative synaptic connection with an undamaged neuron

Question 5

Pruning

Answer 5

the elimination of synaptic connections
that are not adequately activated

Question 6

Synaptic plasticity in learning

Answer 6

the process of acquiring knowledge,
skills, or behaviours through experience

Question 7

Synaptic plasticity in memory

Answer 7

the process of encoding, storing, and
retrieving information that has been previously encountered

Question 8

There are two forms of synaptic plasticity that underlie learning and memory.

Answer 8

long-term potentiation
long-term depression.

Question 9

Long-term potentiation

Answer 9

the long-lasting and experience-dependent strengthening of synaptic
connections that are regularly coactivated

Question 10

Long-term depression

Answer 10

the long-lasting and experience-dependent weakening of synaptic
connections between neurons that are not regularly coactivated
