Q

How was working memory demonstrated in animals?

A

Visual delayed match-to-sample working memory task

17
Q

What is LTP a mechanism for?

A

Long-lasting activity dependant changes in synaptic strength

18
Q

What does D,L-AP5 do?

A

Slows acquisition in water maze
Blocks spatial memory form
Blocks LTP in hippocampus

19
Q

What are the phases of LTP?

A

Induction
Early LTP
Late LTP

20
Q

What does long term depression do?

A

Decrease the efficacy of synaptic neurons so learning can continue

21
Q

Is LTP associative or dissociative?

A

Associative

22
Q

Is LTD associative or dissociative?

A

Dissociative

23
Q

Where are new neurons born into?

A

The denate gyrus
