Memory and the Hippocampus

Question 1

What causes the synapse to change during long term potentiation?

Answer 1

The NMDA receptor

Question 2

What receptor contains magnesium?

Answer 2

The NMDA receptor

Question 3

What binds to both AMPA and NMDA receptors?

Answer 3

Glutamate

Question 4

2 long lasting cellular changes induced by calcium

Answer 4

1. Production of more AMPA receptors
2. Transport of intracellular AMPA receptors to the cell membrane

Question 5

What causes opening of calcium channels in an NMDA receptor?

Answer 5

Repeated depolarization in AMPA receptors (caused by binding of glutamate)

Question 6

The reinstatement of memory from a partial cue

Answer 6

Pattern completion

Question 7

In what way is the hippocampus connected to the cortex?

Answer 7

Bidirectionally

Question 8

Process in which information is temporarily stored in the hippocampus via LTP

Answer 8

Encoding

Question 9

Process in which information is gradually transferred from the hippocampus to the cortex

Answer 9

Consolidation
