A

Significant memory loss

18
Q

How many layers does the hippocampus have?

3

19
Q

What is the Hebbian synapse concept?

A

There is a change in the efficacy of synapses during memory formation

20
Q

What is long term potentiation?

A

Long term increase in synaptic strength

21
Q

What is long term depression?

A

Long term decrease in synaptic strength

22
Q

What can cause long term potentiation?

A

Simultaneous stimulation of the pre and postsynaptic neuron

23
Q

What is habituation?

A

Decreased response as a result of repeated gentle stimulation - learn to not react

24
Q

How does long term potentiation occur?

A

Involved trafficking of AMPA receptors to the postsynaptic membrane
