Question 5

two types of receptors important for memory

Answer 5

AMPA and NMDA

Question 6

AMPA

Answer 6

• not critical for learning , but it precedes NDMA

- Necessary for activation of NDMA

Question 7

NMDA

Answer 7

• is critical for memory

- If AMPA is inhibited then it blocks NDMA from being activated

Question 8

Tagging

Answer 8

Cell A and cell B, interact with one other early on

• Cell A: HPC
• Cell B: OFC

Question 9

AP 5

Answer 9

a selective NMDA receptor antagonist that competitively inhibits the ligand binding site of NMDA receptors. AP5 blocks NMDA receptors in micromolar concentrations.
