_____ occurs when patterns of neural activity are re-expressed when something is remembered:

Answer 5

Reactivation

Question 6

Answer 7

Fire; wire

Question 8

What type of artificial electrical stimulation can be used to strengthen synaptic connections?

Answer 8

Question 9

LTP produces changes in receptor & synapse shape, which assist in the strengthening of synaptic connections between neurons. True or false?

Answer 9

True

Question 10

In order to test whether LTP _____ memory, we could show that blocking LTP ____ memory formation: (weakens; strengthens; prevents; increases)

Answer 10

Strengthens; prevents

Question 11

Which drug could be administered in order to demonstrate that reversing LTP produces forgetting?

Answer 11

ZIP (Zeta-inhibitory peptide)

Question 12

Which NMDA antagonist could be administered to demonstrate that blocking LTP prevents memory formation?

Answer 12

AP5

Question 13

AP5 is an _____ of NMDA: (agonist, antagonist)

Answer 13

Antagonist

The idea that synaptic connections between coactivated cells change in a manner dependent on activity is known as what law?

Answer 15

Hebb’s law

Question 16

Which three excitatory pathways, found in the hippocampus, operate in memory functioning?

Answer 16

The perforant pathway; the mossy fibres; the Schaffer collaterals
