Unit 3, Aos 1, Dp 4 - 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

Sprouting (synaptic plasticity)

Answer 2

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

Question 3

Rerouting (synaptic plasticity)

Answer 3

• ability of a neuron connected to a damaged neuron
• to create an alternative synaptic connection with an undamaged neuron

Question 4

Pruning (synaptic plasticity)

Answer 4

• elimination of synaptic connections
• that are not adequately activated

Question 5

Long-Term Potentiation

Answer 5

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

Question 6

Long-Term Depression

Answer 6

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